Answer:

The equation in slope intercept form (y = mx + b) is y = 2x - 4

m = the slope

b = the y intercept

The line cross the y-axis at -4 so the y-intercept (b) is -4.

You can use the slope formula
(y_(2)-y_(1) )/(x_(2)-x_(1) ) since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.

(0--4)/(2-0) =
(4)/(2) = 2

So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4
