The equation is y=2x+4.

Work Step by Step

You are given the point (-3,-2) and the slope is 2.Use the equation of line in point-slope form (y-$y_{1}$)=m(x-$x_{1}$).Put the value of m and the point in the equation: y-(-2)=2{x-(-3)] -simplify- y+2=2(x+3) -distribute- y+2=2x+6 subtract 2 from both sides- y=2x+4 The y-intercept is (0,4) and the slope is 2.Start at (0,4) and go up 1 and over to the right 1. Plot the points and connect them with a straight line.
