(4,5) and (2,3) Find Slope using given points M = (y2-y1)/(x2-x1)
M= (3-5) / (2-4)
M= -2/-2
M=1
y = mx + b use Slope intercept form and any above point either one (i am using (2,3))
3 = 1(2)+b solve for b
b = 1
y= x+1 ANSWER
Hey Brett -- you could try a visual approach ... passing from 2,3 to 4,5 means rising 2y for every 2x ... slope is 1 ... now back down from 2,3 -- 1,2 -- 0,1 ... y-intercept is 1 ... Graphically, the line looks like y=x but is offset up by 1 ==> y= x+1 ... Regards :)
