(2,4) and (6,6) what is the equation of the line y=

Find the slope, m = (y2y1)/(x2x1).
Then use the equation y  y1 = m(x  x1) with either point to find the equation of the line. 
so what is y= then?

it also says im supposed tp find an equation of the line containing the given pair of points?

Marth actually told you a way to do it
slope = m = (64)/(62) = 2/4 = 1/2
so
y  y1 = m(x  x1)
y  4 = (1/2)(x2)
2y  8 = x  2
2y = x + 6 
a drop from 100 to 50 is 50. a rise 50 to 100. will the percent of decrease and the percent of increase be the same.
