Pls help with this graph

y = x + 3

Step-by-step explanation:

This question is simply asking you to find the slope in y=mx+b form.

Slope is rise over run. Because for each time the graph goes up one, it goes two to the left, the slope is . Therefore, your (mx) is x.

Your y-intercept, or b, is where the line intersects the y, or vertical, axis. Therefore, it would be 3.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

b
