Study Guide - Radical Equations & Parallel / Perpendicular Lines

Front

What is a radical equation?

Back

A radical equation is an equation in which a variable is contained within a radical (square root, cube root, etc.).

Front

How do you isolate a radical in an equation?

Back

To isolate a radical, you can move all other terms to the opposite side of the equation and then simplify.

Back

Multiply both sides by 3 to eliminate the fraction.

Back

x = 2.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

How do you find the slope of a line given its equation in slope-intercept form?

Back

The slope is the coefficient of x in the equation of the line, which is in the form y = mx + b.

Front

Back

The slope is -3/5.

How do you write the equation of a line parallel to a given line?

Back

Use the same slope as the given line and the point-slope form of the equation.
