Answer:

z = -2.685

Step-by-step explanation:

First combine like terms

-7.52+5.5= -2.02

Now you have:

-2.02+8z= -23.5

which if you add 2.02 on both sides you should get

8z = 21.48

so you divide 8 on both sides which is

z= -2.685

Z= 2.685
8x-2.685= -21.48
-21.48+5.5-7.52= -23.5

Slope=-4, it goes through (-2,9)

Answer:

y= -4x+1

Step-by-step explanation:

If you want to write this equation in slope intercept form, you need to find the y-intercept. Here is your current equation y= -4x + b. Then, substitute the x and y for the coordinate. Now, it should look like this: 9= -4(-2) + b. Multiply -4 and -2 to get 8. Now, this is your equation: 9= 8 + b. Then, subtract 8 from both sides to get your final answer, 1=b. Now that you have your y-intercept, go back to your original equation and fill in 1 for b. This is your final equation: y= -4x+1. Hope this helped!
