Topics for Today:
One of the most recognizable forms of a line is the slope-intercept form. This line form is very useful because it's easy to visualize the actual line simply by looking at the equation. From slope-intercept form, you can tell if the slope is positive or negative, and if the slope is steep or shallow, and also it demonstrates where the line crosses the y-axis (this is the y-intercept).We talked about what an intercept is (this word sounds an awful lot like intersect!).
I reminded students of our work on solving literal equations - this skill will be especially helpful for our unit on linear equations, as we'll be looking at three different forms for a linear equation. To put a line in slope-intercept form, simply solve for the variable "y".
Slope intercept form looks like this: y=mx + b
- m is the slope
- b is the y-intercept
Vocabulary: linear equation, y-intercept, slope-intercept form
