Question

The graph of a line has a slope of 3 and passes through the point (-4, -5).

What is the equation of the line in point-slope form?

A. y + 5 = 3(x + 4)
B. y - 5 = 3(x - 4)
C. y + 4 = 3(x + 5)
D. y - 4 = 3(x - 5)

Thank you, everyone!

Answer 1

A. y+5 = 3(x+4)

Explanation:

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

m=slope(3)

y1=-5

x1=-4

y-(-5)=3(x-(-4)) - two negatives = positive

y+5=3(x+4)
