Answer:

1

Step-by-step explanation:

So for this type of problem we use the formula m= \frac{y_{2}-y_{1}  }{x_{2}-x_{1} } with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be y_{2} in this case.) First, let's define which is which:

(3,2): x_{1}, y_{1}

(-2,-3): x_{2}, y_{2}

Now we need to replace the variables with their known values: m=\frac{-3-2}{-2-3}

Next, let's do the subtraction to simplify: m=\frac{-5}{-5}

And we can complete the division (all fractions are division!) to simplify even further: m = 1

Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.

Explain how slope is used to determine if a triangle is a right triangle.
Bond [772]

A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle.
