Unformatted text preview: ® Exertisé score: o..aF'1 pt_ Find the intercepts and then use them to graph the equation. y=-5-5X Assignmenf scare: 7996; (24.5 0F_31 pt‘s) Use the graphing tool to graph the line Use the intercepts when drawing the hue. If only one intercept eXists, use it and another point to draw the line. B! m _31 gfal complg Find the intercepts and then use them to graph the equation. ﬁy=3X- 18 Question is complete. "Span-Ir. showing Now, to graph the equation, you plot the intercepts. Plot (0, — 3). Plot (6,0) Now, to complete the graph, draw a line through the points you plotted. Always remember to plot a third point in order to make sure your graph is correct. To ﬁnd the coordinates of a third point, you simply substitute a value of X into the given equation and solve for y. For eXample, let X = 2. First, substitute 2 for X and solve for y. ﬁy=3X- 18 ﬁy=3(2)- 18 by: - 12 y=—2 s (2, - 2) is a solution and should be on the line. Plot (2, - 2). Note that (2, - 2) is on the line. Thus, the correct graph ofthe equation is shown on the right. 1‘ Question is complete. ...
