 Question 2685: Find the equation of the line that passes through points (7,-2) and (5,-1) Write the equation of the line in slope-intercept form. I know the the slope intercept for is y = mx +bAnswer by kiru_khandelwal(79)   (Show Source): You can put this solution on YOUR website!Equation of the line passing through two points (x1,y1) and (x2,y2) is (y-y1)/(x-x1) = m where m = slope of the line = y2-y1/x2-x1 Sp the equation of the line will be (y-y1)/(x-x1) = (y2-y1)/(x2-x1)...........equation(1) According to the question x1 = 7 y1 = -2 x2 = 5 and y2 = -1 substituting these values in equation(1) => (y-(-2))/(x-7) = (-1-(-2))/(5-7) => (y+2)/(x-7) = 1/(-2) => 2(y+2) = -(x-7) => 2y + 4 = -x + 7 => 2y = -x + 3 The eqation of line in slope intercept form which is y=mx+c will be y = -x/2 + 3/2
