Answer:

a. How did you graph each linear equation in two variables?

To graph a linear equation by plotting points, you need to find three points whose coordinates are solutions to the equation. You can use the x- and y- intercepts as two of your three points. Find the intercepts, and then find a third point to ensure accuracy. Make sure the points line up—then draw the line.

b. How do you describe the graphs of linear equations in two variables?

The graph of a linear equation Ax+By=C is a line. Every point on the line is a solution of the equation. Every solution of this equation is a point on this line.
