(2,4) and (6,6) what is the equation of the line y=
Find the slope, m = (y2-y1)/(x2-x1).
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 = (6-4)/(6-2) = 2/4 = 1/2
y - y1 = m(x - x1)
y - 4 = (1/2)(x-2)
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.
