Number 22: We'd plot the first point at 0 since there is no stated y-intercept. Next, we'd use our slope to determine where to plot the next point, and that would create our line. According to the problem, our slope is [tex] -\frac{1}{2} [/tex], which automatically tells us that the slope would be going downwards because it's negative.
To plot our point, use the slope while going down and across from our y-intercept, which is 0. Go down 1, and over 2.
Your points should be at (0, 0) and (-1, 2)
Number 23: This one will be a bit trickier since the equation is not in slope-intercept form. First, let's convert it to slope-intercept form.
Flip some of those numbers around to get our equation in slope-intercept form:
[tex]y = \frac{2}{3}x + 2[/tex]
Now to graph this, we do the same as we did for the last problem. Plot our first point at (0, 2), since 2 is our y-intercept. Afterwards, go up 2 and over 3, then plot the other point.
