The points are (-1, 7) and (2,10) First, get the slope (m) m = (Y1-Y2)/(X1-X2) m = (7-10)/(-1-2) m = -3/-3 m = 1 using the slope-intercept formula, let's get x intercept (b) y = mx + b 7 = 1(-1) + b 7+1 = b b = 8 So we have m = 1, b = 8 y=mx+b y = x + 8 y - x = 8 So the answer is letter C. -1x + y = 8
