Get the equation of the line

10/26/2020

What is the equation of line that has a slope of 2, and contains the point (4,6) ?

Substitute the coordinates and slope into slope-intercept form, to find the y-intercept.

y = mx + b
6 = 2(4) + b {substituted into slope-intercept form}
6 = 8 + b {multiplied 2 by 4}
b = -2 {subtracted 8 from each side}

slope = 2 and y-intercept = -2
y = 2x - 2 {substituted slope and y-intercept into slope-intercept form}
