Answer:

y = 2x + 4

Step-by-step explanation:

We see immediately tht the y-intercept is (0, 4).  As we move from (-2, 0) to (4, 4), x (the run) increases by 2 and y (the rise) by 4.  Thus, the slope of the line is m = rise / run = 4/2 = 2, and so we can immediately write the specific version of the slope-intercept equation y = mx + b as y = 2x + 4.
