Question

Guys please, I can't go to sleep until I finish this :(

A) Identify two points on the line and write the coordinate pairs below.
B) Use your two points to find the slope, and make sure to show your work.
C) Use your slope from Part B and find the equation of the line in point-slope form. Show your work and work through the steps to transform the equation from the point-slope form into the slope-intercept form.
D) Based on the equation you found in Part C, predict how long it takes Mr. Waxman to deliver his packages on Day 0. Approximately how much did his delivery time decrease per day?

Answer 1

(4,19) (7,7)

Slope = -4

Y=-4x+35 (This is point slope intercept form, sorry but could you please convert this?)

35 minutes, 4 minutes a day

Explanation:

You take the coordinates you see for A, in this case, the last 2

The slope you find with the equation y2-y1/x2-x1, so substitute 7-19/7-4 = -12/3=-4.

As for this, (please convert I'll find out later but you need this answer now so....)

For 35 minutes, if you know your y intercept is 35, then it will be (0,35) for 5 minutes. Also, the slope is -4, so you know that it decreases by 4 minutes.

Answer 2

point a- (7,7)

point b- (4,19)

slope- m=-12/3=-4/1=-4

equation of line- y=4x+35

time - 48min on day 0, and it increases by 12min a day
