A line with a slope of 2 passes through the point (3, –4). What is its equation in slope-intercept form?

Answer 1

Hi Alicia!

Note that the equation for slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

First, we plug in the coordinate (3, -4) and the slope of 2 into the equation to get the y-intercept:

-4 = (2)(3) + b

-4 = 6 + b

b = -10

Therefore, the equation in slope-intercept form is: y = 2x - 10
