We spent today working on reading the slope and y-intercept from equations for lines. In an equation like
the slope is and the y-intercept is 4.
We practised plotting that y-intercept on a coordinate grid and then using the slope to “step” along the line, plotting other points that were also on the line. In the above example, we moved to the right 2 (the run) and down 3 (the rise; it’s down because the slope is negative).
Take a look at yesterday’s post for the a video explaining how this works.
We completed this page and graphed all 12 lines:
Here are the blank graphs, 6 to a page:
