8th Grade Math Mid Year Review

Front

What is the first step to solve the equation: -3x - 11 = 44?

Back

Add 11 to both sides.

Front

Given f(x) = -4x - 10 and f(x) = 10, find x.

Back

x = -5.

Front

Find the slope and y-intercept of the equation: 2x - 3y = -12.

Back

Slope = 2/3, y-intercept = 4.

Front

What is the slope of the equation: 5x + 10y = 30?

Back

m = -1/2.

Front

Which equation has x = 2 as a solution? 3 + x = 10, 11 + x = 13, 4x = 32, 5x = 25.

Back

11 + x = 13.

Front

What is the definition of slope in a linear equation?

Back

Slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

How do you find the y-intercept of a linear equation?

Back

Set x = 0 in the equation and solve for y.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does it mean for an equation to have a solution?

Back

A solution is a value of the variable that makes the equation true.

Front

What is the process to isolate a variable in an equation?

Back

Use inverse operations to get the variable alone on one side of the equation.
