The slope, m, of a linear equation can be found using the formula m = v2 - v1/x2 - x1 , where the x- and the y-values come from two ordered pairs, and (x1,y1) and (x2,y2). What is an equivalent equation solved for y2?

A. y2 = mx2 - x1 + y1

B. y2 = mx2 - x1 - y1

C. y2 = m(x2 - x1) + y1

D. y2 = m(x2 - x1) - y1

HELP PLEASE

Answer asap and if you do you will get brainliest. catherine buys a gallon of ice cream from the store. after taking it home, she eats a fifth of a gallon of ice cream. her sister eats some of the ice cream as well. if two-thirds of the original amount of ice cream is left, then what fraction of a gallon of ice cream did her sister eat?
