SOMEONE HELP PLEASE! 50 POINTS!

A line with a slope of 2 passes through (3,9). Which choice is an equation of this line?

A. y − 3 = 2(x − 9)
B. y + 9 = 2x + 3
C. y − 9 = 2(x − 3)
D. y - 9 = 2x - 3

Answer 1

The point-slope form of the equation of a line with slope m through point (h, k) is

... y - k = m(x - h)

Substituting your given values of m=2 and (h, k)=(3, 9) gives you

... C. y - 9 = 2(x - 3)
