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

Where:
m: It is the slope of the line
b: It is the cut point with the y axis
We have the following points:

We find the slope:

Thus, the equation is of the form:

We substitute a point and find b:

Finally, the equation is:

Answer:

A.
30+40+50+60= 180
180 divided by 4equals 45
Their fore the answer is A
