Which graph shows a rate of change of 1/2 which is a fraction between –4 and 0 on the x-axis?

irakobra [83]

By definition, we have that the average rate of change is given by:

$AVR = \frac{y2-y1}{x2-x1}$

Substituting values we have:

$AVR = \frac{3-1}{0-(-4)}$

Rewriting we have:

$AVR = \frac{2}{0+4}$

$AVR = \frac{2}{4}$

$AVR = \frac{1}{2}$

Therefore, the graph that has an AVR of 1/2 is the graph of the linear function.

Answer:

graph shows a rate of change of 1/2 is the linear function

Y=x+2 4x+3y= -36 system of equation

Free_Kalibri [48]

Answer:

(-6, -4)

Step-by-step explanation:

Use substitution.

Since y is already isolated, substitute it into the y of: 4x+3y=-36.

You should get: 4x+3(x+2)=-36

Simplify this and you'll get:

4x+3x+6=-36

Add both of the variables:

7x+6=-36

Add -6 to both sides, (because there is a -36 on one side, and a 6 on the other, you have to add a negative to eliminate the 6 whilst adding to the -36)

7x=-42

Divide both sides by 7:

x=-6

Now substitute this into y=x+2

y=-6+2

y=-4
