Flashcard 4 - Next Generation Quantitative Reasoning, Algebra, and Statistics Flashcard Set for the ACCUPLACER Test


The correct answer is:

Point-slope form: \((y - y_1) = m(x - x_1)\)
Slope-intercept form: \(y = mx + b\)
General form: \(Ax + By = C\)


The slope of a line, m, is the ratio of the change in y-values to the change in x-values: \(m = \frac{y_2 - y_1}{x_2 - x_1}\).
Lines are one-dimensional objects of the general form \(y = mx\); they can be positive and slope upward to the right, or negative and slope downward to the right.
A slope of \(0\) is a horizontal line, and an infinite slope is a vertical line.
