Question

What are the slope and y-intercept of the line? Question 2 options:

Slope = 6, y-Intercept = 170
Slope = -170, y-Intercept = 1020
Slope = 1020, y-Intercept = -170
Slope = 170, y-Intercept = 6

Answer 1

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.
