Agraph is shown below: a graph is shown. the values on the x axis are 0, 3, 6, 9, 12, and 15. the values on the y axis are 0, 9, 18, 27, 36, and 45. points are shown on ordered pairs 0, 36 and 3, 27 and 6, 18 and 9, 9 and 12, 0.
these points are connected by a line.
what is the equation of the line in slope-intercept form?
a. y = 36x − 3
b. y = −3x + 36
c. y = −3x + 12
d. y = −12x + 3
