A-REI

3 - Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.

This tutorial is intended for Algebra 1 students in high school (grades 9-10).

Tutorial

Use this site for some of the questions. This provides an introduction to the design and information regarding the slope-intercept for of a line.

.

The following questions can be answered using this page, which goes into further detail about linear equations.

.

Use this page to manipulate the slope and y-intercept of linear equations to see how these values affect the resulting graph.

.

Should either these sites fail, read through this site (consists of three pages) to get your information

.

**Reflect on your explorations and research when answering these questions:**

.

1) First, consider the slope of a vertical line. Justify in your own words why the slope of a vertical line is what it is.

.

2) Design several linear equations in slope-intercept and describe them graphically using proper terminology.

.

3) Consider the point-slope form of a line and the slope-intercept form of a line. Explain how we can arrive at the slope-intercept form of a line from the point-slope form of a line.
