Polygon mnopq is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image m′n′o′p′q′. the coordinates of point m are (2, 4), and the coordinates of point n are (3, 5). the slope of is .

Which point lies on a circle with a radius of 5 units and center at p(6, 1)?

Evaluate the expression for the given value of the variable. 5×(h+3) for h=7
