WebSolving simultaneous linear equations using straight line graphs. The 2 lines represent the equations '4x - 6y = -4' and '2x + 2y = 6'. There is only one point the two equations cross. Because the graphs of 4x - 6y = 12 and 2x … WebIf the line goes straight up, then the line's equation is in the form x = ? because only the y value changes, the x value never changes. The x intercept is all you need to calculate for the equation because that x value is the same x value for every point on the line. So if your x intercept is (5,0) then your line's equation would be x = 5. WebJust two points are needed to draw a straight line graph, although it is a good idea to do a check with another point once you have drawn the graph.
