Question

If WXYZ is a rectangle, Z is located at (-4,-5) and Y is located at (-1,-7), find the slope of WX

Answer 1

STEP 1

we find the slope of ZY

`\text{Slope(ZY) =}\frac{y_2-y_1}{x_{2\text{ }}-x_1}=(-7-(-5))/(-1-(-4))=(-2)/(3)`

STEP 2

We find the slope of WZ

Since WZ is perpendicular to ZY

Therefore slope of WZ

`\text{Slope(WZ) = }\frac{-1}{\text{Slope(ZY)}}\text{ = }(-1)/((-2)/(3))=(3)/(2)`

Therefore the correct answer is B
