Find the value of r so that the line that passes through (r,-5) and (3, 13) has a slope of 8. a. (-18/5) b. (3/4) c. 6 d. -141

Slope = Change in y/ Change in x.

8 = (13 - -5) / (3 - r)

8 = 18/(3 -r)

3 - r = 18/8

3 - r = 9/4

3  - 9/4 = r

3 - 2 and 1/4 = r

3/4 = r

r = 3/4   B.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
