Chapter 3 - Part 1 Review

Front

What is the slope of a line in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0.

Front

Find the slope of the line that passes through the points (1, 2) and (3, 4).

Back

The slope is 1.

Front

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

For the function f(x) = 2x + 3, what is f(1)?

Back

f(1) = 5.

Front

What does it mean if a line has a slope of 0?

Back

It means the line is horizontal and does not rise or fall.

Front

What does it mean if a line has an undefined slope?

Back

It means the line is vertical and cannot be expressed as a ratio of rise over run.

Front

Find the y-intercept of the equation 3x + 2y = 6.

Back

The y-intercept is 3.

Front

What is the slope of the line that passes through the points (2, 3) and (2, 5)?

Back

The slope is undefined.

Front

For the function f(x) = -x + 4, what is the slope?

Back

The slope is -1.
