Front

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

Back

The slope is 2.

Front

What does 'b' represent in the equation y=mx+b?

Back

The 'b' represents the y-intercept.

Front

Is the point (3,11) on the graph of y=2x+5?

Back

Yes, the point (3,11) is on the graph.

Front

Identify the slope and y-intercept of the equation y = 3 - x.

Back

Slope: -1, Y-intercept: 3.

Front

Is this table a function or not a function?

Back

It is a function.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

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

Back

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

Front

What does it mean for a relation to be a function?

Back

A relation is a function if each input has exactly one output.

Front

What is the y-intercept of the equation y = 4x + 2?

Back

The y-intercept is 2.

Front

How can you determine if a graph represents a function?

Back

Use the vertical line test; if a vertical line crosses the graph more than once, it is not a function.
