To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points.

Graphing a Linear EquationPlug x = 0 into the equation and solve for y.Plot the point (0,y) on the y-axis.Plug y = 0 into the equation and solve for x.Plot the point (x,0) on the x-axis.Draw a straight line between the two points.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Graphing a Line in Standard Form The first approach is to change the equation to slope-intercept form and then graph it. The second approach is to use standard form to find the \\begin{align}x\\end{align} and \\begin{align}y-\\end{align}intercepts of the line and connect the two.

What is the first step in graphing a linear equation in slope intercept form? Draw the line that connects the two points. Use the slope to find a second point and plot it. Locate the y-intercept on the graph and plot the point.

Graphing a Line Using the Slope and Y-InterceptFind the y-intercept = b of the equation y = mx + b.Plot the y-intercept. The point will be (0, b).Find the slope=m of the equation y = mx + b.Make a single step, using the rise and run from the slope.Connect those two points with your line.
