Write the slope intercept form equation from the graph.

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the image, the line goes through the following points:

So, the slope is:

Thus, the equation is of the form:

We substitute a point and find "b":

Finally, the equation is:

if x decreases by 4 then y increases by 10
