you will get this = x^2 + 3x- 7x- 21 ,then u collect the like terms which is (3x & -7x).

your answer ( x^2 - 4x - 21 ).

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
