Graphing a Linear Equation in Slope-Intercept Form

A linear equation or linear function in slope-intercept form has the following form.
The slope and intercept are used to graph the equation. Consider the following function.
There are three steps to follow to graph it.
1
Plot the Intercept
expand_more
The intercept can be used to find the the first point the line passes through.
The intercept is Plot the point on a coordinate plane.
The point (0,-3) plotted on a coordinate plane
2
Use the Slope to Plot the Second Point
expand_more
There should be at least two points to draw a line. The second point can be plotted on the coordinate plane by using the slope Based on the equation, the slope is
This means that the rise is and the run is
From the first point move unit right and units up to plot the second point.
Two points (0,-3) and (1,-1) on the coordinate plane
3
Draw a Line Through the Points
expand_more

Finally, use a straightedge to draw a line through both points.

A line with the equation y=2x-3 passing through the points (1, -1) and (0, -3).

This line is the graph of
