Question

29. Find the missing coordinate that would result in the given slope. (x, 2) and (5, -4) if m= -3​

Answer 1

Set up an equation (you can use the distance formula as an equation). The distance formula is Y2-Y1/X2-X1.

2-(-4)/x-5=-3

6/x-5=-3

Multiply both sides by x-5.

6=-3(x-5)

Distribute the -3 to the terms in the parentheses.

6=-3x+15

Subtract 15.

-9=-3x

Divide both sides by -3.

3=x

So, the missing number of the coordinate is 3.
