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

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

anonymous · Answer

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) :)
