AFDA Review #2

Front

What is the formula to calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

Find the slope of the line that passes through (-4, 7) and (-6, -4).

Back

11/2

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

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

Front

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

Back

D: {-4, 0, 1, 2}, R: {-4, -3, 1}

Front

What does the equation y = mx + b represent?

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

Identify the slope and y-intercept in the equation y = 1/4 x + 2.

Back

Slope (m) = 1/4, y-intercept (b) = 2

Front

What is the range of the graph represented by -3 ≤ y < 1?

Back

The range includes all y-values from -3 to just below 1.

Front

What is the domain of a linear function?

Back

The set of all possible x-values for which the function is defined.

Front

Find the domain of the linear function that is defined for -6 ≤ x ≤ 6.

Back

The domain is all x-values from -6 to 6, inclusive.
