.....in order to graph this function, you need two points
take any 2 values for and find
if ....->..
if ....->..
so, one point is (0,0) and another one is (1,-3)
plot these points and draw a line through

hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (0, 0) and (x2, y2) = (1, -3).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(-3)x + (0)

Your graph:
