14. find the slope of the line passing through the points (8, 15) and (5,9).

We have and .

The slope is

Hope this helps.

The slope is 2.

Step-by-step explanation:

Slope, usually represented by m, is m = rise / run.

If we go from the point (5, 9) to the point (8, 15), x increases by 3 (this is the run) and y increases by 6 (this is the rise).  

Thus, the slope is m = rise / run = 6/3, or 2.

The slope is 2.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
