Answer:

y=4x-4

Explanation:

1. Start by putting the coordinates and the slope into point-slope form. Remember, m represents slope and y1 and x1 represent the x and y coordinates from the point (3,8).

y-y1=m(x-x1)

y-8=4(x-3)

2. Simplify the equation by distributing the 4 to (x-3) and adding 8 to both sides.

y-8=4x-12

y=4x-4

3. y=4x-4 is your answer
