5(x−2) Notice that the equation in point-slope form is not solved for y. Case 3 You know two points on the line. 1. Start with the equation in point-slope form y−y0 =m(x−x0). 2. Find the slope using the slope formula. m =y2−y1 x2−x1 3. Plug in the value of the slope. 4. Plug in the x and y values of one of the given points in place of ...

1. Use the Distance Formula 2. Use the Midpoint Formula Examples: 1. Find the distance between the points (-3,7) and (4,10). 2. Determine whether the triangle formed by points A=(-2,2), B=(2,-1), and C=(5,4) is a right triangle. 3. Find the midpoint of the line segment joining the points P1=(6,-3) and P2=(4,2). Teaching Notes:
Find the distance between points D and F, and the slope of the line they form. Find the distance between points A and B, and the slope of the line they form.
Example: The distance between (3, 4) and (x, 7) is 5 units. Find x. Using the distance formula: (3 —x)2 + (4—7) x) 3 Solving Graphically (Pythagorean Theorem) Example: b b 3 -5 4 or -4 The length of segment AB is 20. If the coordinate of Ais (5, 1), and the coordinate of B is (-6, y), what is b? Using the distance formula: 1) 400 279 121 ...
