First, find the slope of your line: m= y2-y1/x2-x1: m= 5-3/4--1 m= 2/5
Second, choose a point and plug into y=mx+b to solve for b (y-intercept). y=mx +b 5 = 2/5(4) +b 5 = 8/5 +b Subtract 8/5 to both sides. 5-8/5 = b find commondenominators & subtract. 25/5 -8/5 =b 17/5 =b
Your final answer/equation of the line is: y = 2/5x + 17/5
