Question

What is an equation of the line

A. Y+3=2(x+2)
B. Y+5=1/2(x+2)
C. Y-3=1/2(x-2)
D. Y+3=2(x-2)

Answer 1

A, y + 3 = 2(x + 2)

Explanation:

Point slope form is y -y1 = m(x - x1)

To find the equation for this line, plug in y1, m, and x into the equation.

m = 2

y1 = -3

x1 = -2

y - -3 = 2(x - -2)

Since subtracting a negative changes the sign to a positive, the equation becomes:

y + 3 = 2(x + 2)

This is option A.
