1 STAAR Categor Grade Mathematics TEKS.A Student Activit Work with our partner to answer the following questions. Problem : Complete the table below to show the slope and -intercept of each equation. Equation Slope -intercept 0.. Problem : A larger number is less than times a smaller number. Write an equation to represent this situation. Let represent the larger number. Let represent the smaller number. A larger number is less than times a smaller number The equation that represents the relationship between the two numbers is. Graph the equation on the grid below. The graph will be a. The line will cross the -ais at or at (, ). The slope of the line will be. From an point on the graph, if ou move unit right then ou must move units to locate another point on the line s graph TEKSING TOWARD STAAR 0 Page
2 STAAR Categor Grade Mathematics TEKS.A Problem : What is the equation of the line graphed below? (, ) (, ) (0, ) The line crosses the -ais at so that is the value of in the equation = m + b. As increases unit, then increases units. Therefore, the line has a slope of. The equation of the line is =. Substitute the values of (, ) in the equation. Do the make the equation true?
