Answer: y=5/4x+13
Step-by-step explanation:
Slope-intercept form:
y= mx+b
Where x and y are the points, m is the slope, and b is the y-intercept.
Plug in the points to find the y-intercept.
-5= 5/4(-8)+b
Solve.
-5= 2.25(-8)+b
Combine like terms.
-5=-18+b
Add 18 on both sides.
13= b
Now you have the y-intercept. Plug in every point except the x and y, because you wouldn't be able to graph it if you had just numbers. (not that you have to; that is just the correct form)
y=5/4x+13
