Graphing Linear Equations in Standard Form
Graph the line -2x + 3y = -6
We can find the x and the y intercepts of the line by the following:
- First, let . This can be done by writing it out, but it is easier to just cover up the x-term with your finger as if it isn't even there. Divide both sides by 3 to get . Plot the point on the y-axis. Click on and plot the point.
- Next, let . Once again, it is easier to just cover up the y-term with your finger. Divide both sides by -2 to get . Plot the point on the x-axis.
- Now, click on the icon in the menu to create a line the goes through both points.
Find the slope of -2x + 3y = -6
Now that the line has been graphed, let's find the slope of the line.
- Using the formula, , plug in the coordinates of the two points.
- On the menu, click on the icon and then arrow down to the icon Slope. Click on the line. The slope will be displayed as a decimal rounded to two decimal places.
