Finding X and Y Coordinates on a Graph
Slope Intercept Form and Finding the slope
Tutoring Algebra, slope and intercepts
We looked at slope intercept form and how m is the slope and b is the y- intercept. To get the y-intercept, you set x = 0 to get the x-intercept, you set y = 0 To get the slope, you use two points …

Knowing a little can help a lot (to look things up) in math
Tutoring precalculus, We started by looking at problems with sets of equations. The first were sets of linear equations. Others had quadratics. For one problem, if you recognized part of the …
