Use the graph to write a linear function that relates y to x

Answer:
y = -4x -2
Step-by-step 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
