Question

PLEASE HELP!!!

Look at the graph below. Determine the equation, then choose the correct interpretation for the y-intercept, x-intercept, and slope.

Not all choices will be used.

Answer 1

Explanation:

Use the points (0, 165) and(3, 0) to find the slope

m = slope = (0 - 165)/(3 - 0) = -55

equation of the line in slope-intercept form: y = mx + b, where b is the y-intercept

y = -55x + 165 choice c

y-intercept is 165 (miles) choice b

x-intercept is 3 (hours) choice a

slope is -55 (miles/hr) choice d

Note: the first point on the graph should be (0, 165) not (165, 0) as shown
