Front

Write an equation of a line that passes through the point (5,-1) and is parallel to the line y = (-3/5)x -3

Back

y = (-3/5)x + 2

Front

What is the definition of a parallel line?

Back

Two lines that have the same slope and never intersect.

Front

What is the absolute value of a number?

Back

The distance of that number from zero on the number line, always non-negative.

Front

How do you simplify a radical expression?

Back

Factor the number under the radical into its prime factors and simplify by taking out pairs.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) for two points (x1, y1) and (x2, y2).

Front

What does it mean to evaluate an expression?

Back

To calculate the value of the expression by substituting the variables with given numbers.
