Answer:

y=2x-19

Explanation:

I'm guessing you mean slope intercept form y=mx+b

If so, first you would have to find the slope of the line

To do that, use the formula y2-y1/x2-x1

Remember you can pick any coordinate pair for this

I will pick 1=y2 -5=y1 10=x2 and 7=x1

When I put that in the equation I get 1-(-5)/10-7

Overall I get 6/3, or 2

Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)

I will pick (10,1)

1=y and 10=x and 2=m

1=2(10)+b

this simplifies to 1=20+b

now subtract 20 from both sides and get -19 = b

Now you have your equation y=2x-19
