finding slope and y intercept practice

Front

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

Back

The slope is represented by 'm'.

Front

What does a linear function look like on a graph?

Back

A linear function is represented by a straight line.

Front

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

Back

The y-intercept is -3.

Front

How do you identify the y-intercept from a graph?

Back

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

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line.

Front

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

Back

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

Front

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

Back

The y-intercept is 5.

Front

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

Back

A slope of 0 means the line is horizontal.

Front

What is the slope of a line that goes down from left to right?

Back

The slope is negative.

Front

How can you tell if a graph represents a function?

Back

A graph represents a function if it passes the vertical line test.
