Slope ratio from Point A to toe of slope opposite Point A: 39.68% or 2.52/1. Cut from the back of sidewalk to the invert of sewer lateral at the property line: C-3 76'. Distance from the north property line to toe of slope at point B: 5.66'.
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 each pair of points uing Pythagorean Theorem. (Sketch a graph and plot the points first). Also, determine the slope between the two points for review. 11) ( , ), ( , ) 12) ( , ), ( , ) 13) ( , ), ( , )
Section 1: Distance & Slope The distance between two points is the length of the line segment that connects them. 1. Find the distance between the points (1,−2) and (6,−2). graphically algebraically =√( T 6− T 5) 6+( U 6− U 5) 6 2. (Find the length of the line segment with endpoints 8,−6) and (4,0). graphically algebraically
1)2 + (y 2 y 1)2 (1) where P = (x 1;y 1) and Q = (x 2;y 2), say. Let’s consider an example. Example Find the shortest distance from P=(-1,3) to x y + 5 0. Solution Step 1: We need to nd the equation of the line through P and perpendicular to x y + 5 = 0. We need to nd the slope of the line. x y + 5 = 0 y = 5 x y = x+ 5 Therefore, the slope is ...
