Grade 8 slope is rise over run: the constant rate of change along a nonvertical line. Students compute slope from two points or a table, write y = mx + b, and use slope to test parallel and perpendicular lines. In a context, slope is a unit rate such as dollars per hour or miles per gallon.

What you practice

These are the Grade 8 Slope & Linear Relationships skills this quiz is built around.

Compute slope from two points or from a table using change in y over change in x.
Write the equation of a line in slope-intercept form from slope and a point or intercept.
Determine whether two lines are parallel, perpendicular, or neither from their slopes.

A useful tip

Slope is (y2 − y1)/(x2 − x1). Reversing only one coordinate, or subtracting in opposite orders, flips the sign and is a common calculation mistake.
