Answer:
y = 5x - 22 is the answer
y - intercept is -22.
Step-by-step explanation:
Given:
Slope: 5
Point: (3, -7)
Unknown:
Equation = ? = y = mx + b
y - intercept = ?
Step 1. Input the coordinates into the equation of y = mx + b.
y = 5x + b
y-coordinate = -7
x-coordinate = 3
-7 = 5(3)+b
Step 2. Solve for b.
-7 = 15 + b
-15 -15
b = -33
Step 3. Make the y equation.
y = mx + b
mx = 5x
b = -22
y = 5x - 22
y = 5x - 22 is the answer
y - intercept is -22.
