18Find the x and y intercept point according to the table.1. Press [2 nd ] then press [Tblset], In this situation, enter -10 for Tblstart and 1 for▲Tbl =2. Press [2 nd ] then press [TABLE]3. Now look for when x = 0 and where y = 0. These are your intercepts on the x andy axis. In this situation you can find that x-intercept = -5 and y-intercept = 5.X/Y Intercepts
19Directions: With your calculator, graph each equation and find the x and y intercepts.Once you find the x and y intercepts by the graph, check it by looking at your table.Once you have finished the problems, get together with your group and discuss youranswers. Then with your groups answer the questions at the bottom. Make sure that yourequations are solved for y in terms of x before graphing.1. y = 5x – 152. y = -2.5x + 6.53. 8x + 10y = 304. y = 1/2x + 15. y = 1.95x – 12.05Group work:1. What kind of line has no y-intercept?2. If the x-intercept of a line is positive and the y-intercept is negative, does the lineslat up or down from left to right? Explain your reasoning.3. What did you notice about the intercepts and slope in relation to the equation?Answer Key:
