Answer:
The y-intercept is -15.
Step-by-step explanation:
y - 5 = 5(x - 4) is our equation in point-slope form.
point slope form is = y - y1 = m( x - x1)
So, we know that the slope is 5 and one point is (4, 5)
We can use this point and the slope to find the y -intercept.
y = mx + b is slope intercept form.
Let's input the values we know to find the y-intercept.
5 = 5(4) + b
5 = 20 + b
-15 = b
The y-intercept is -15.

Answer:
A.
Step-by-step explanation:
m = y2-y1/x2-x1
m = 12-4/15-5
m = 8/10
m = 4/5
