Answer by Alan3354(31518)   (Show Source): You can put this solution on YOUR website!writing slope-intercept form of a line through points (1,-3) and (0,4). ------------- Find the slope, m m = diffy/diffx = 7/(-1) m = -7 ------ Use y = mx + b and either point to find b, the y-intercept -3 = -7*1 + b b = 4 --> y = -7x + 4 =================== If you know determinants: |x +y 1| |1 -3 1| = 0 |0 +4 1| ------------ (Plus signs for alignment) x*(-3 - 4) - y*(1 - 0) + 1*(4 - 0) = 0 -7x - y + 4 = 0 y = -7x + 4
