Question

Choose the equation below that represents the line passing through the point (2, -5)with a slope of -3.
Answer







y = -3x - 13








y = -3x + 11








y = -3x + 1








y = -3x + 13

Answer 1

use the point slope form

y- y1 = m(x-x1)

y1 = -5
x1 = 2
m = -3

substitute then turn to general form

Answer 2

Just plug 2 for x and -5 for y and see which equation is true.

Answer 3

Or, since the slopes are -3 in all the options, you can just substitute x=2 and y=-5 and check which option is correct.
