Weby=mx+b. In this equation, 'm' is the slope and 'b' is the y-intercept. To graph a line from a slope-intercept equation, take the value of the slope and put it over 1. For example, if the slope was 5, the slope would be 5/1. Next graph the y-intercept, take the number that is the y-intercept, and graph that number on the graph. WebDec 8, 2024 · Make it into a y= equation first. so. −3x + 3x +7y = 21 +3x. 7y 7 = 3x + 21 7. y = 3x 7 +3. From this equation, we can see that this line would have a y intersection at 3. So label the point at (0,3) We also know that the coefficient before the x represents the slope. So slope is 3/7.

WebDec 1, 2024 · 1. Use the y=mx+b formula. To graph a linear equation, all you have to do it substitute in the variables in this formula. [1] In the formula, you will be solving for (x,y). The variable m= slope. The slope is also noted as rise over run, or the number of points you travel up and over. In the formula, b= y-intercept. WebAug 21, 2024 · Find values for x and y then plot the graph. Start by separating y on the left side of the equation. This gives you: y = -3x-1 Next set up plot points. Since this is a linear equation, you only need 2 points. … WebApr 9, 2024 · The equation x = − 2 has a graph that is a vertical line with all x -coordinates equal to −2. The collection of points with x -coordinate (strictly) greater that −2 is to the right of this line. The graph of the inequality is shaded in blue. The vertical line x = − 2 is dashed rather than solid to indicate that the line is not included. the play football
