Back

-2

Front

Solve the inequality -4 + y < -8.

Back

y < -4

Front

What is the constant of proportionality (slope) in a linear equation?

Back

The slope is the ratio of the change in y to the change in x.

Front

Which graph represents a linear function?

Back

Graph D is linear.

Front

What is the slope in the equation y=2x + 3?

Back

2

Front

Define slope in the context of a graph.

Back

Slope is a measure of the steepness of a line, calculated as rise over run.

Front

What does it mean for a graph to be linear?

Back

A linear graph represents a constant rate of change and can be expressed in the form y = mx + b.

Front

How do you solve for x in the equation 3x + 5 = 20?

Back

x = 5.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows the relationship between expressions that are not necessarily equal.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).
