Step-by-step explanation:
The function is given :
f(x) = 4x + 15
For f(-3), the input for the function f(x) is -3.
Replace the x variable with -3.
f(-3) = 4(-3) + 15
Evaluate.
f(-3) = -12 + 15
f(-3) = 3
The output for f(-3) is 3.
Given the following question:
Point A = (7, 4) = (x1, y1)
Point B = (3, 6) = (x2, y2)
To find the slope use rise over run:
m = -0.5
