Question

Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.

y - 1 = 4(x - 3)

y + 1 = 4(x + 3)

y - 3 = 4(x + 1)

y + 3 = 4(x - 1)

Answer 1

point slope form

y - y1 = m(x - x1)

m is the slope
(x1, y1) is the point the line goes through

Answer 2

isnt x and y where it goes through?

Answer 3

no it's (x1,y1)

Answer 4

x and y are left as they are

Answer 5

the slope is 4, so m = 4

Answer 6

the given point the line goes through is (-3, -1)

so

x1 = -3
y1 = -1

Answer 7

okay....i dont understand what to do with that information...

Answer 8

you plug it into the equation y - y1 = m(x - x1)

Answer 9

ie you replace m with 4, x1 with -3, y1 with -1

and you simplify
