Answer:
y = 4/3x - 12
Step-by-step explanation:
To find the slope of the line, we do (y2 - y1) / (x2 - x1)
If we put in the values, we'll get
(-4 - -8) / (6 - 3)
Simplify and get
(-4 + 8) / 3
4 / 3
Your slope is now 4/3, so you can put it into your equation y = mx + b
y = 4/3x + b
To find b, we can plug in the values from one of your points. Lets use (3, -8)
-8 = 4/3 * 3 + b
Now solve the equation
-8 = 4 + b
-12 = b
Now that you have b, your equation is complete:
y = 4/3x - 12
-5x - 35 = 0
-5x = 0 + 35
-5x/-5 = 35/-5
X = -7
