Me ; -; complete the point-slope equation of the line through (1,-1) and (5,2). )=

slope  = (y2-y1)/(x2-x1)

      =  (2--1)/(5-1)

      = (2+1)/(4)

       =3/4

The point slope from of a line is

y-y1 = m(x-x1)

y--1 = 3/4 (x-1)

y+1 = 3/4 (x-1)

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
