Question

Will give a medal! A line has a slope of -3 and passes through the point (5, -1). What is the equation of the line?
My guess is -3x + 2 = -2

Answer 1

yes I believe the equation you use is y=mx+b

Answer 2

You use point-slope form
y-y_1 = m(x-x_1)

Answer 3

ok so it is something y - x = 14

Answer 4

Nope.
y-1=-3(x-5) is it in point-slope form
Distribute what's in the parentheses to get
y-1=-3+15
add 1 to both sides
y=-3x+16
