Points C(−5, 8) and D(2,5) lie on line CD. If points C′ and D′ are created by translating points C and D left 6 units, what is the slope of line C′D′? A. 3/7 B. −3/7 C. 7/3 D. −7/3

Consider the line y=x. If the line is dilated by a factor of 2, what is the equation of the resulting line? If the resulting line is translated 3 units up, what is the equation of the resulting line? Please answer!~

Which pair of lines are parallel? Select all that apply. A. y=3−2xy=2x−3 B. y=2x−1y−2x=8 C. y−4x=6y+4x=−6 D. y=−3x+1y+4x=x−1
