Answer:

y = -4x -2

Explanation:

There is a dot on the y-axis at y=-2, so that is the y-intercept. The next dot to the right is 1 unit right and 4 units down, so the slope is ...

m = rise/run = -4/1 = -4

The slope-intercept equation for the relation is ...

y = mx +b . . . . . line with slope m and y-intercept b

y = -4x -2
