Graphing Linear Equations Problems Graph the following using the method (if given) 1. y 3x 7 (using substitution method) 2. 3x 4y 12 (using intercepts method) 3. 2x 4y 8 (using slope-intercept method) 4. The line passing through (-2, -1) and has a slope of 3 2. 5. x 0 6. y 2 7. Choose any two points on the line x = 7 and find the slope. 8.
Standard form is great for finding the x and y intercepts of a graph, that is, the point where the graph crosses the x-axis and the point where it crosses the y-axis. Also, when solving systems of equations -- finding the point where two or more functions intersect -- the equations are often written in standard form.
When it comes to graphing linear equations, there are a few simple ways to do it. The simplest way is to find the intercept values for both the x-axis and the y-axis. Then just draw a line that passes through both of these points. That line is the solution of the equation and its visual representation.
