This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing …

Learn how to graph lines whose equations are given in the slope-intercept form y=mx+b. If you haven't read it yet, you might want to start with our introduction to slope-intercept form.

Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). Topics you'll explore include the slope and the equation of a line.

To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3).

Positive and negative linear associations from scatter plots Estimating equations of lines of best fit, and using them to make predictions Interpreting slope and y-intercept for linear models

Since we have a low (<1) coefficient inside the function, the graph will horizontally get squished, or vertically stretch. So our correct graph should be less steep than a normal absolute value …

There are three main steps to this: find the slope, find the "y"-intercept (where the graph crosses the "y"-axis), and put those values into the formula y=mx+b.
