Answer:

this is what i thought of

Step-2. Rate of change, or slope, is the change in y over change in x. Remember that a point is given in (x, y). Also that you need two points to find the change.

If you have two points, (x1, y1) and (x2, y2), the rate of change or slope would be 

.

In your problem, the given points are (0, -1) and (2, -11).

Using the formula for rate of change, the rate of change would be:

.

The "initial value" is the y-intercept - where the graph intersects the y-axis and also where x = 0. The given point (0, -1) has x = 0, so the initial value is -1.

4. Remember the model equation for a graph of a line is

y = mx + b,

where m is slope and b is y-intercept - where the graph intersects the y-axis and also where x = 0.

The x-axis of the graph would be number of weeks, since it is independent.

The y-axis of the graph would be how much money she has.

Since she starts (at 0 weeks) at $25, the first point would be (0, 25). Notice here that it is the y-intercept since x = 0. The value of b in the model equation of a line y = mx + b would be 25.

The rate of change, or slope, is $5/week. This is m in the model equation of a line y = mx + b.

Putting b = 25 and m = 5 into the model equation y = mx + b (remember we use this equation because it works for all lines), the equation would be

y = 5x + 25.

4.

The slope of this will be -0.5degrees/hr, or just -0.5 if it is used as m in the 

y = mx+b equation. The slope is negative because it "decreases".

5. 

Plot each point and connect the dots. Remember the first number corresponds to the x-axis and the second to the y-axis.

For example in the table for x = -2 and y = -6, the point is (-2, -6), and from the origin (0,0) you go left 2 on the x-axis and down 6 to plot the point.

9.

I think you can do this if you can do #3, but now you have to find b by plugging in given values.

y = mx + b

y = 1212x + b

We can plug in the given point (3,1) to find b.

1 = 1212(3) + b

b = -3625

y = 1212 - 3625

10. Don't know which function you are referring to.

The slope is $10/week, or m = 10.

A point is (4, 90) because "After 4 weeks, Roberta has $90."

The y-intercept is 50 because x (weeks) = 0 at that time.

y = mx + b

y = 10x + 50

Which expression is not equivalent<br> to (x + 4)(x – 3)?
Digiron [165]

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

{x }^{2}  - 3x + 4(x - 3)

2) Expand by distributing terms.

{x}^{2}  - 3x + 4x - 12

3) Collect like terms.

{x}^{2}  + ( - 3x + 4x) - 12

4) Simplify.

{x}^{2}  + x - 12

<em><u>The</u></em><em><u> </u></em><em><u>second</u></em><em><u> </u></em><em><u>equation</u></em><em><u> </u></em><em><u>are</u></em><em><u> </u></em><em><u>equivalent</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>equation</u></em><em><u>.</u></em><em><u> </u></em><em><u>but</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>first</u></em><em><u> </u></em><em><u>equation</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>not</u></em><em><u> </u></em><em><u>equivalent</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>m</u></em><em><u>a</u></em><em><u>i</u></em><em><u>n</u></em><em><u> </u></em><em><u>equation</u></em><em><u>.</u></em>

The pair of points (6,y) and (10,-1) lie on a line with a slope 1(over)4. What is the value of y?
Viktor [21]
The formula for Slope is m = \frac{y_2 - y_1}{x_2 - x_1} where m is the slope and the x's and y's are your given coordinates. So, plug the given information into the formula and solve for y.

m = \frac{y_2 - y_1}{x_2 - x_1}   Plug in the given values
\frac{1}{4} = \frac{-1 - y}{10 - 6}   Cross multiply
10 - 6 = -4 - 4y   Subtract
       4 = -4 - 4y   Add 4 to both sides
       8 = -4y        Divide both sides by -4
      -2 = y            Swich the sides to make it easier to read
       y = -2

Check your answer by plugging -2 back into the equation with the other values.

[<span>tex] \frac{1}{4} [/tex] = \frac{-1 - (-2)}{10 - 6}   Simplify the double negative
</span><span>\frac{1}{4} = \frac{-1 + 2}{10 - 6}   Simplify the numerator and denominator
</span><span>\frac{1}{4} = \frac{1}{4}
</span>
Since both sides equal each other, y = -2.
