y=2x+1

Explanation:

When given the slope and and a point of the line, you can use point-slope form to find your linear equation.

y-y_1=m(x-x_1)

m is your slope and (x_1,y_1) is your point.

All you have to do is plug in the numbers and simplify the equation.

y-9=2(x-4)

y-9=2x-8

y=2x+1

And there's your answer!
