Answer: y = - 0.4 x - 4.5
Step-by-step explanation:
Equation y=mx+b
m is the slope
x is *ANY* x coordinate
y is *ANY* y coordinate
b is y intercept or WHERE the point is on the Y AXIS
Lets look at the given:
Slope (m) is -2/5
Passes through point 15, -9/2
As you can see, the point goes through the Y axis at (-9/2)
Our equation is y = - 0.4 x - 4.5
