 Question 535018: find the equation of the line going through (-1,5), and (3,7), and graph the line.Answer by mananth(12270)   (Show Source): You can put this solution on YOUR website!x1 y1 x2 y2 -1 5 3 7 slope m = (y2-y1)/(x2-x1) ( 7 - 5 )/( 3 -1 ) ( 2 / 4 ) m= 1/ 2 Plug value of the slope and point ( -1 , 5 ) in Y = m x + b 5.00 = - 1/2 + b b= 5 - 1/2 b= 9/ 2 So the equation will be Y = 1/2 x + 9/2 y= 0.5 x + 4.5 Plot the points x 0 2 3 y= 4.5 5.5 6 (x,y) (0,4.5 ),(2,5.5),(3,6 ) m.ananth@hotmail.ca
