70=3/5
times 5/3
350/3
this is 7/8
350/3=7/8
times 8/7 both sides
400/3

that is 5/6
400/3=5/6 of total
times 6/5 both sides
800/5=160

kate had 160 originally

Answer:

Slope- intercept form   y = 200 x + 500

Step-by-step explanation:

Given that the equation

       200x - y + 500 = 0

where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours

The slope-intercept form

                y = m x +C

Given equation  200x - y + 500 = 0

                          200 x + 500 =y

                       y = 200 x + 500

Slope of the equation m = 200 and y-intercept 'C' = 500
