Question

What is the equation of the line that has a slope of 2 and passes through the point (2,9)?

A. y - 2 = 2(x + 9)
B. y + 2 = -2(x - 9)
C. y + 9 = -2(x + 2)
D. y - 9 = 2(x - 2)

Answer 1

D

Explanation:

use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)

we're given that m=2 and the point is (2,9)

Substitute into the equation

y-9=2(x-2)

That means that the answer is D

Hope this helps!
