WebGraph of an Equation in Two Variables A point (x, y) satisfies the equation if it makes the equation true when the values for x and y are substituted into the equation. For example, the point (3, 10) satisfies the equation y = x 2 + 1 because 10 = 3 + 1. However, the point (1, 3) does not, because 3 ≠ 12 + 1. WebRemember in the example y = 1 2 x + 3, we carefully chose values for x so as not to graph fractions at all. If we solve the equation 2 x + y = 3 for y, it will be easier to find three solutions to the equation. The solutions for x = 0, x = 1, and x = −1 are shown in the Table 4.13. The graph is shown in Figure 4.9.
