Let's first find the y intercept in two ways. The first way is simply looking at the equation because it's in slope intercept, y = mx +b. In Slope intercept, b is the y intercept, therefore it is 4.
Another way is noticing that in a y intercept, x is always 0 because that's where the line crosses the y axis and there's no x value. So, if we plug in x for 0, we get y = 4.
Now for the x intercept. In an x intercept, y is zero because it's where the line crosses the x axis. Therefore, we plug in y as 0:
0 = x + 4 -4 = x
Therefore, the x intercept is (-4,0) and the y intercept is (0, 4).
