I don't understand this question lol so confusing I also suck at math

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 .

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

Bring the fraction a/a-4 to a denominator of 16-a^2
