Part 2-Slope and Y-Intercept

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, y).

Front

How do you find the y-intercept from a linear equation in slope-intercept form?

Back

In the equation y = mx + b, the y-intercept is the value of b.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the formula for calculating slope?

Back

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

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates a vertical line.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

The slope is 2.

Front

What is the y-intercept of the line represented by the equation y = -4x + 5?

Back

The y-intercept is 5.

Front

How can you determine the y-intercept from a graph?

Back

Locate the point where the line crosses the y-axis.

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

The slope is 2.
