Question

What is an equation in point-slope form of the line that passes through (–3, –1) and has a slope of 2? A. y − 1 = 2(x − 3) B. y + 1 = 2(x + 3) C. y – 1 = 2(x + 3) D. y + 1 = 2(x – 3)

Answer 1

B

Explanation:

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

x1=-3

y1=-1

m=2

Now plug it in!

y-(-1)=2(x-(-3))

Simplify it to

y+1=2(x+3)

Therefore, it should be B

Hope this helps!
