What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other. For example, a > 4 means 'a is greater than 4'.

How do you solve the inequality 2a + 3 < 11?

Back

To solve the inequality, subtract 3 from both sides: 2a < 8. Then divide by 2: a < 4.

What is the formula to find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Given the points (3,2) and (4,7), what is the slope?

Back

The slope is 5, calculated as (7 - 2) / (4 - 3).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1. This means that one line's slope is the negative reciprocal of the other's.

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

Back

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

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.

What does the term 'slope' refer to in a graph?

Back

The slope refers to the steepness or incline of a line on a graph, indicating how much y changes for a change in x.
