5.2 Slope, y intercept, Graphing Part 1

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, b) where b is the value of y when x = 0.

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept from an equation in the form y = mx + b, set x = 0. The value of y at this point is the y-intercept.

Front

What does the slope of a line represent?

Back

Front

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

Back

The slope of the line is 3.

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

The slope of the line is -2.

Front

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept, plot it on the graph, and use the slope to find another point. Draw a line through these points.

Front

What is the formula for slope-intercept form?

Back

Front

What is the y-intercept of the equation y = 4x - 1?

Back

The y-intercept is -1, represented as (0, -1).

Front

What is the y-intercept of the equation y = -3x + 6?

Back

The y-intercept is 6, represented as (0, 6).

Front

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

Back

A slope of 0 indicates that the line is horizontal and does not rise or fall as x changes.
