Can someone help me?

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

Which composition of similarity transformations maps polygon abcd to polygon a'b'c'd'? a dilation with a scale factor less than 1 and then a reflection a dilation with a scale factor less than 1 and then a translation a dilation with a scale factor greater than 1 and then a reflection a dilation with a scale factor greater than 1 and then a translation

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
