Question 40897
x-values are the grams of acid produced
y-values are the minutes taken to make the acid
(3,32) and (9,48)
This can be looked at as many ways, but I will do a linear line:
m = (y2 - y1)/(x2 - x1) = (48 - 32)/(9 - 3) = 16/6 = 8/3
Use slope-intercept form:
{{{y = mx + b}}}
{{{32 = (8/3)(3) + b}}}
{{{32 = 8 + b}}}
{{{24 = b}}}
so ....
{{{y = (8/3)x + 24}}}
{{{ graph( 500, 500, -5, 10, -5, 50, (8/3)x + 24) }}}
