linear equation formulas
Term | Definition |
---|---|
find slope given two points | m = Change y/change x |
point-slope form of a linear equation | y-ysub1 = m(x - xsub1) |
slope-intercept form of a line | y = mx + b |
Standard form of a line | Ax + By = C |
2 differences between slope-intercept and standard form | slope-intercept can use rational numbers where standard can only use integers. Slope-intercept is solved for y. Standard has x and y on same side. |
