The video tutorial explains how to graph linear equations and determine the number of solutions for systems of equations. It covers finding x and y intercepts, graphing lines, and analyzing the solutions. The first system of equations results in infinite solutions as the lines coincide, while the second system has no solution due to parallel lines with different intercepts.

What is the first step in graphing a linear equation?

• Find the slope

• Determine the intercepts

• Plot random points

• Calculate the midpoint

How do you find the x-intercept of a linear equation?

• Solve for the slope

• Set y to zero and solve for x

• Set both x and y to zero

• Set x to zero and solve for y
