Slope/Y-intercept Review

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

In the equation y = -4x - 3, what is the value of b?

Back

-3

Front

What does the slope (m) represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

If the slope of a line is 1/2, what does this indicate about the line?

Back

For every 2 units the line moves horizontally, it moves 1 unit vertically.

Front

What is the slope of a horizontal line?

Back

0

Front

What is the slope of a vertical line?

Back

Undefined.

Front

In the equation y = mx + b, what does the term 'b' represent?

Back

The y-intercept, which is the point where the line crosses the y-axis.

Front

If a line has a slope of -2, how does it behave?

Back

It decreases; for every 1 unit increase in x, y decreases by 2 units.

Front

What is the slope of the line represented by the equation y = 2x + 1?

Back

2

Front

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

Back

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