Answer: No, it is not a right triangle.

Explanation:
9^2 + 7^2 (?) 12^2

81 + 49 (?) 144

130 = 144

Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.

How do you find the constant rate of change
Anon25 [30]
Rate of change = \frac{y2 - y1}{x2 - x1}
So grab 2 Y's first and then subtract
7 - 3 = 4
and do the same for X
4 - 2 = 2
Simplify
4/2 = 2
2 is your rate of change
