Back

The slope of the line.

Front

What is the slope of a line?

Back

The steepness or incline of the line, calculated as the rise over run.

Front

What is the y-intercept in a linear equation?

Back

The value of y when x is 0, represented by 'b' in the equation y = mx + b.

Front

Write the equation for a line with a slope of 4 and a y-intercept of 3 in slope-intercept form.

Back

y = 4x + 3

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What does a slope of zero indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

Front

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

Back

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

Front

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.
