Question 44869
x-values are the amount of items
y-values are the cost
(100,10000) and (300,22000)
M = (y2 - y1)/(x2 - x1) = (22000 - 10000)/(300 - 100) = 12000/200 = 60
Point-Slope Form
{{{y - y1 = m(x - x1)}}}
{{{y - 10000 = 60(x - 100)}}}
{{{y - 10000 = 60x - 6000}}}
{{{y = 60x + 4000}}}
{{{ graph( 600, 600, -50, 300, -500, 22000, 60x + 4000) }}}
