1: Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions. 2: Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
When you graph inequalities that have only one variable, we use a number line. We will use open and closed circles and arrows pointing to the left or right Pay special attention to the part where we divide by negative 1. Our last example revisits how to solve equations and/or inequalities with fractions.
