Question

The graph of a line has a slope of –3 and passes through the point (–6, –4). What is the equation of the line in point-slope form?

y + 4 = –3(x + 6)
y – 4 = –3(x – 6)
y – 6 = –3(x – 4)
y + 6 = –3(x + 4)

Answer 1

Do you know what point slope form is?

Answer 2

not exactly

Answer 3

y=mx+b

Answer 4

Ok, point slope form is used to find the equation of a line given a slope and a point.
