Answer:

y = 8x + 4

Step-by-step explanation:

y=mx+b

m=8

y = 8x + b

We just need to find b. B is where the line intersects the y- axis. On the y-axis by definition, the x-coordinate =0 but that is not helpful now...

Let's re write and try to solve for b. That means write as b = ...

y = 8x + b

b = y - (8x)

Substitute for x and y the numbers of the coordinates of the given point (3,28):

b = y - (8*x)

b = 28 - (8*3)

b = 28 - 24

b = 4

So the answer is y = 8x + 4
