Graphing Linear Equations - Extra Practice Here with Answers
Step 1) Identify the y-intercept from the equation. Plot that point on the coordinate plane first. Step 2) Identify the slope from the equation. Use the slope to find the next points from the y-intercept you just plotted. Step 3) Make sure your line matches the slope (slanted up for a positive slope, slanted down for a negative slope). Step 4) Pick a couple points that you graphed on the line and plug their coordinates into the equation for the line. This will be how you check to make sure the points you graphed are actually supposed to be on the line. Writing Linear Equations Step 1) Find where the graph crosses the y-axis. This will be the y-intercept. The y-intercept is always the y-coordinate when the x-coordinate = 0. Step 2) Find the slope between any two points on the graph. Step 3) Fit the pieces together into slope-intercept form (y=mx+b). Step 4) Pick a couple points that were graphed on the line and plug their coordinates into the equation you found for the line. This will be how you check to make sure the equation matches the line that was graphed.
