 Question 575955: Find the equation of the line passing through the points (3, 5) and (2.8, 6). Here is what I did: (x1 is 3, y1 is 5), (x2 is 2.8, y2 is 6) A. Slope = y2 - y1/x2 - x1 Slope = 6 - 5/2.8 - 3 = 1/-0.2 = -5 B. y = mx + b I picked ordered pair (3, 5) to find the y-intercept. 5 = -5(3) + b 5*-5 = -5*3 + b -25 = -15 + b -25 - (-15) + b = -10 C.
