$\textsf{Let's calculate the slope of the line passing thought the points (-4, 4) and (-6, 6) } \\ \textsf{using the following formula: }\mathsf{m = \frac{\Delta y}{\Delta x}} \textsf{ where m is the slope of the line.}$ $\textsf{So:}$

$\mathsf{m = \dfrac{\Delta y}{\Delta x} = \dfrac{4 - 6}{-4 - (-6)} = \dfrac{-2}{2} = -1}$

$\textsf{Hence the slope is -1.}$

Which pairs of rectangles are similar polygons?

kobusy [5.1K]

the longer side / the shorter side must be the same for rectangles to be similar.

For A: 105 / 80 = 1.32

For B: 120 / 90 = 1.33

For C: 100 / 75 = 1.47

So... only A and B are similar.
