Back

Vertical

Front

Write the equation for the line given the slope of 4 and y-intercept of 3.

Back

y = 4x + 3

Front

Determine the slope and y-intercept for the equation y = (3/2)x + 3.

Back

Slope: 3/2, Y-intercept: (0, 3)

Front

Is the graph pictured a function?

Back

Yes

Front

What is the domain of the graph if it is defined for 1 ≤ x ≤ 4?

Back

1 ≤ x ≤ 4

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does the y-intercept represent in a graph?

Back

The point where the line crosses the y-axis.

Front

What is the range of a function?

Back

The set of all possible output values (y-values) of a function.
