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
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. ...
