Lesson Summary:
In this lesson, you will learn how to graph and shade inequalities involving two variables in the x, y coordinate plane. The video provides step-by-step guidance on how to plot the y-intercept and slope, draw the line, and shade above or below it based on whether the inequality is greater than or less than. The instructor also demonstrates how to solve for y when the inequality is given in terms of x and y. By the end of this tutorial, you will be able to confidently graph and interpret inequalities in two variables.
