Front

What is the point where the line crosses the y-axis called?

Back

Front

What is the slope of the line in the equation y = -2x + 6?

Back

-2

Front

Which equation represents the graph that has a negative slope and crosses the y-axis at -3?

Back

y = -5x - 3

Front

What does the slope of a line represent in a graph?

Back

The rate of change of y with respect to x.

Front

What is the x-intercept of a line?

Back

The point where the line crosses the x-axis.

Front

How do you find the y-intercept from the equation of a line?

Back

Set x = 0 and solve for y.

Front

What is the general form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

If the slope of a line is 4, what does this indicate about the line?

Back

For every 1 unit increase in x, y increases by 4 units.

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.
