Linear Equations Practice

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean to solve a linear equation?

Back

To solve a linear equation means to find the value of the variable that makes the equation true.

Front

What is the slope in a linear equation?

Back

The slope (m) is a number that describes the steepness and direction of a line. It is calculated as the rise over run.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept (b) is the point where the line crosses the y-axis. It represents the value of y when x is 0.

Front

Solve for y: 15 = 3y.

Back

y = 5.

Front

Solve for x: 5x = 25.

Back

x = 5.

Front

Solve for x: x + 3 = 9.

Back

x = 6.
