Answer: SLOPE=-170, Y-INTERCEPT = 1020
Explanation:
Calculate the slope: Take any two points and find the changes in x and y:
I'll use (4, 340) and (6, 0):
Change in y (the rise) is (0 - 340) = -340.
The change in x is (6-4) = 2
The slope is the rise (y) over the run (x): -340/2 or -170.
The y-intercept is the value of y when x=0. The f=-data provided has a value for y at x=0: (0,1020). So the interecpt is 1020.
