Are the graphs of the lines in the pair parallel? explain. y = 6x + 9 27x – 3y = –81

the answer is No, because the slopes are not the same

Step-by-step explanation:

in the equation: y=6x+9

the slope is 6

in the equation: 27x - 3y= -81

the slope is 7

the slopes are NOT the same

the answer is 48m^2!

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
