Use the scratch pad to work out the intercepts. For Ax + By = C, set y = 0 to find the x-intercept and set x = 0 to find the y-intercept. Enter both ordered pairs using the number pad. A and B divide C evenly, so the intercepts are integers. Once all four coordinates are entered, switch to Graph. Plot both intercepts, then tap Graph line and Check graph. Both intercept entries and the graph must be correct for a star.
Earn at least 10 correct and a best streak of 6 for 10/10. Once you have 10 correct, you may submit or keep practicing. Your score is your correct total (up to 10), minus one point for each streak step missing from 6. Ten correct with a best streak of 4 earns 8/10. Your best streak in this session counts even if it ends later.
