Answer:

y = 5x - 22 is the answer

y - intercept is -22.

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.

Hope it helped,
