8th Grade NWEA Math Review

Front

What is the distributive property in algebra?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

Simplify the expression: 3(3x + 1)

Back

9x + 3

Front

What are like terms in algebra?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

Front

Combine the like terms: 3x + 2x + 3y - 7y

Back

5x - 4y

Front

What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented by the value of y when x = 0.

Front

Find the y-intercept of the line: y = -2x + 4

Back

Front

What is the formula to find the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.

Front

Find the slope of the line that passes through the points (6,7) and (4,2).

Back

5/2

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

Write the equation of the line with a slope of 1/3 and a y-intercept of -2.

Back

y = 1/3x - 2
