Ani spent a total of $7.53 at a store. She bought some cereal for $3.67. She also bought 6 peaches.

Ratling [72]

Answer:

Step-by-step explanation:

It says she spent $7.53 at the store and she bought (SOME) cereal for $3.67

so we have to find how much the 6 peaches cost. To find it out we are going to have to subtract the cereal she bought from $3.67 and the money she wasted total so its going to be D.

Can you help me find the answer for slope

pav-90 [236]

Step-by-step explanation:

How you find the slope of a straight line, depends on what information you are given. Here are some pieces of information you might be given and how to find the slope in each:

two random points

* Use the formula for slope and substitute each of the x and y values.

$slope = m = \frac{{y_2}-y_{1}}{x_{2}-x_{1}}$

Ex: given points (1,2) and (3,4)

$m = \frac{{y_2}-y_{1}}{x_{2}-x_{1}}$

$m = \frac{4-2}{3-1}$

$m = \frac{2}{2}$

$m = 1$

picture of the graph

* You can choose two random points on the graph and do two random points method

* OR you can use another formula for slope: m = rise/run

First, choose two random points on the graph that are on the grid lines. Count distance between first and second point. (The first point being on the left side.)

- Count how far away the two points are vertically. This number is "rise". If the second point is under the first point, the rise is a negative number.

- Count how far away they are horizontally. This is the "run". This number will not be negative.

Divide the number for rise by the number for run to get the slope.

random point and the y-intercept

* Use slope-intercept form and substitute the random point and the y-intercept

y = mx + b

Substitute the y-coordinate of the point for y, the x-coordinate of the point for x, and the y-intercept for b.

Isolate m to find the slope.

Ex: given (2,1) and y-intercept (0, 0)

y = mx + b

1 = m2 + 0

1 = 2m

m = 1/2

5.) Write the equation Slope: y-intercept: equation:

zloy xaker [14]

Answer:

Slope = 2/3

y-intercept = 1

The equation in slope intercept form is y = 2/3 x + 1

OR y = 2x/3 + 1

Step-by-step explanation:

m is the slope. b is the y-intercept.

Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 2/3 and the y-intercept is +1

Step-by-step explanation: To find the slope, m, determine "rise over run"

Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (–3,–1), (0,1) and (3,3)

The "rise" is the difference in y-values. Here, they increase by 2.

The "run" is the difference in x-values. Here they increase by 3.

So the slope is 2/3. Put that in place of m in the equation

The graphed line crosses the y-axis at +1

That is the y-intercept. Use +1 in the place of b

Keep the y and x; substitute the values for m and b we found.

y = 2/3 x + 1

y = 2/3+ 1 This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be multiplied by 2 and divided by 3.
