so the points are (x,f(x)) (-3,-1) (0,2) (3,5) (6,8) hmm, find slope slope betweeen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1) slope betwen (0,2) and (3,5) Is (5-2)/(3-0)=3/3=1 y=mx+b m=slope b=y intercept given slope=1 y=1x+b find b input a point (3,5) x=3 and y=5 5=1(3)+b 5=3+b 2=b y=1x+2 is the equaiton
