The slope of (-5,-4) (5,3)

Work Shown:

The two points given are (x1,y1) = (-5,-4) and (x2,y2) = (5,3)

Use them in the slope formula

m = (y2 - y1)/(x2 - x1)

m = (3 - (-4))/(5 - (-5))

m = (3 + 4)/(5 + 5)

m = 7/10

∆DPL ~ ∆QAZ

Step-by-step explanation:

In the diagram given, the following can be deduced:

<D is congruent to <Q

<P is congruent to <A

<L is congruent to <Z

From these, looking at the letter arrangement, the similarity statement can be written as:

∆DPL ~ ∆QAZ
