At a particular restaurant, each pizza roll has 60 calories and each slider has 300 calories. A combination meal with pizza rolls and sliders has a total of 7 pizza rolls
and sliders altogether and contains 900 calories. Graphically solve a system of
equations in order to determine the number of pizza rolls in the combination meal, 2,
and the number of sliders in the combination meal, y.
Please help, like can someone give me the equations and the coordinates
