Question

Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.
A.) y - 1 = 4(x - 3) <---?
B.) y + 1 = 4(x + 3)
C.) y - 3 = 4(x + 1)
D.) y + 3 = 4(x - 1)

Answer 1

y - y1 = m(x-x1)

(x1,y1) = given points
m = slope

Answer 2

so i was wrong?

Answer 3

yeah
because points are (-3,-1), so
y-(-1) = 4(x-(-3))

Answer 4

so it would be c?

Answer 5

y-(-1) =4(x-(-3))
y+1 = 4(x+3)
that would be b

Answer 6

okay can you tell me how you did that ?

Answer 7

-(-1) = +1

Answer 8

multiplication of two negative sign is a positive
