Which equation represents the same line as the points in the table

Answer:

y=\frac{-3}{4} x+2

Step-by-step explanation:

First, we can find the slope using the slope equation and two of the points.

Slope equation:

m=\frac{y2-y1}{x2-x1}

I'm going to use the first two points just so I can avoid the fraction... Substitute the x and y values into the equation.

m=\frac{2-5}{0--4}

Simplify:

m=\frac{-3}{4}

Now that we have the slope, all we need is the y-intercept. Luckily, it gives it to us in the table. The x value of y-intercepts will always be 0. Looking at the table, we see that the point where x=0 is (0,2). Thus, the y-intercept is 2. Your final equation is

y=\frac{-3}{4} x+2

Answer:

y = -3/4x + 2

Step-by-step explanation:

we will choose any two points: (-4,5) and (0,2)

an linear equation should be like this y=ax+b

a is the slope, b is the y intercept

to find the slope we will use this formula: y1 - y2/x2 - x1

2-5/0-(-4) = -3/4

y = -3/4x + b

now you can find the answers by putting the values of x and y from the table

What is the equation of the trend line?k+j
Kaylis [27]
Answer: The equation of the trend line is y = -2x + 24.

First, we need to find the slope. The slope is the change in y over the change in x between the points. Our points move down 4 units while moving right 2 units. So our slope would be -4/2 or just -2.

Second, we need to find the y-intercept. We are lucky because the y-intercept can be see clearly in the graph. It is (0, 24).

We can put the slope and y-intercept together to get the equation:
y = -2x + 24.

Write the set of points greater than or equal to −5−5 but strictly less than 44, excluding 00, as a union of two intervals (if y
Alecsey [184]
What we want to draw is the half closed interval:

                                          I=   [-5, 4) excluding 0,

as the union of 2 different intervals say a and b.

Let a be the interval containing the smallest value.

Then the smallest value of a is -5, and the largest possible value of a is 0, not included, if we want to write a as an interval, without "gaps", or "holes".

So a=[-5, 0)

similarly, b=(0, 4).


Answer: [-5, 4)=[-5, 0)∪(0, 4)

Misha Larkins [42]

Answer:

1) 10

2) 16

Step-by-step explanation:

1) 2x+15=37-2

2x+15=35

2x=35-15

2x=20

2 2

x=10

2)10x-8=9x+8

10x-9x=8+8

x=16

Hope this helps ❤
