Hi There!

Slope Intercept Form: y = mx + b

Point Slope Form: y - y1 = m(x - x1)


Part A:

Find the slope:

y2 - y1/x2 - x1 = m

12 - 21/3 - 6 = -9/-3 = 3

Slope = 3

Slope Intercept Form: y = 3x + 29

Point Slope Form: y - 21 = 3(x - 3)


Part B:

When scott started on Day 1 he was delivering packages every 29 minutes. By the time he reached Day 10 was delivering packages every 2 minutes. Im not entirely sure about this part.


Hope This helps :)

Well, the second point's coordinates are (6,12)

The first point's coordinates are (3,21)

The slope intercept form would be (12-21) / (6-3) which is -3.

The point slope form would be y - 21 = -3(x - 3)




His delivery time decreased by 3 minutes.



Hope this helps!
