Proofs Using Coordinate Geometry 348 Chapter 6 Quadrilaterals What You’ll Learn • To prove theorems using ﬁgures in the coordinate plane. If we start at the x-intercept of point Q, the point (–15, 0), we would follow the slope of –5/3 over 15 and down 25 to (0, –25). This would be the point (–1, 3). Thus, we need a slope that is more than –2/5; another way to say that is, we need a negative slope whose absolute value is less than +2/5. Finish Editing. Each one is a diagonal distance of r = 5 from (5, 3), and if we may a right triangle on either side, the vertical leg is the distance from (5, 3) straight down to the x-axis, which of course is 3. Class Date Proofs Using Coordinate Geometry. 7) Line Q has the equation 5y – 3x = 45.
