Question

Choose the equation below that represents the line passing through the point (2, -5) with a slope of -3.
A) y = -3x - 13
B) y = -3x + 11
C) y = -3x + 13
D) y = -3x + 1

Answer 1

Use point-slope form
\[y - y_1 = m(x - x_1)\]\[y + 5 = -3(x - 2)\]\[y = -3(x - 2) - 5\]Just simplify now.

Answer 2

y=mx+c where m is your slope.

so all of the answers have the right slope.

just sub the point (2,-5) in

so in D) -5=(-3)(2)+1

which gives -5=-5

so your answer is D) :)

Answer 3

ohhh ok thanks so much your a life saver(: math is not my strong point what so ever(:!

Answer 4

You're welcome :)
