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. WebGiven a known (x, y), then the equation is written as m (x - x 1) = y - y 1. The following is slope-intercept form of a line: y = mx + b. In this equation, m is slope and b is the y …
