Answer: Slope is -1

Using the slope formula, we get

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

m = (0 - 4)/(2 - (-2))

m = (0 - 4)/(2 + 2)

m = -4/4

m = -1

What's going on here is that we subtract the y values 0 and 4 to get -4. This means that we dropped 4 units vertically to go from A to B. This is the rise. So rise = -4

The run is 4 because we moved 4 units to the right to go from A to B. This is found algebraically when we subtracted the x coordinates, so 2 - (-2) = 2 + 2 = 4.

Slope = rise/run = -4/4 = -1

You have the correct answer, assuming you wrote -1. I think your teacher just marked it wrong because you forgot to show steps.

The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x. Equilateral me
vladimir2022 [97]

Answer:

Step-by-step explanation:

3*(4x - 3) = 63                         Divide both sides by 3

4x - 3 = 63/3

4x - 3 = 21                                Add 3 to both sides

4x = 21 + 3

4x = 24                                    Divide by 4 on both sides

4x/4 = 24/4

x = 6

Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)
