Front

Write the equation of a line with a slope of -3 and a y-intercept of 8.

Back

y = -3x + 8

Front

Which equation best represents the relationship between x and y in the table: y=5x+5, y=1/5x+5, y=15x+5, y=10x+5?

Front

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

Back

The value of b.

Front

How do you calculate the slope between two points (x₁, y₁) and (x₂, y₂)?

Back

m = (y₂ - y₁) / (x₂ - x₁)

Front

What does the term 'y-intercept' mean?

Back

The point where the line crosses the y-axis.

Front

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

Back

The line is horizontal.

Front

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

Back

The line is vertical.

Front

What is the relationship between the slope and the steepness of a line?

Back

A larger absolute value of the slope indicates a steeper line.
