Algebra: Chapter 7 Review for Chapter Test Tomorrow
Algebra Skills Practice 20 worksheet was started in class and finished for homework.
Remember, to solve problems using the slope-intercept formula, `y = mx + b`, you need to have (or solve first for) the slope, then using one of the ordered pairs given `(x, y)` solve for the y-intercept, b.
Given the slope `m`, and the y-intercept `b`, we can develop the equation by plugging in the values for the slope and the y-intercept.
An equation perpendicular to the given one will have to have its slope be the negative reciprocal for the product to be -1. In other words, `m_1 * m_2 = -1`
A new equation that has to be parallel to the given one, must have its slope be exactly the same, `m_1 = m_2`!
