Unit 4 Algebra Vocab Test

Front

What is an x-intercept?

Back

The point (x, 0) where a line intersects the x-axis.

Front

For the linear inequality shown, will the graph be shaded above or below the line? (y ≤ -x + 11)

Back

Below since the symbol is 'less than.'

Front

What is the point-slope form of a line?

Back

Front

What is the slope-intercept form of a line?

Back

Front

What is a y-intercept?

Back

The point (0, y) where a line intersects the y-axis.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x, indicating how steep the line is.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates 'less than or equal to' or 'greater than or equal to'; a dashed line indicates 'less than' or 'greater than'.

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

Front

What does it mean if a line has a slope of 0?

Back

The line is horizontal, indicating that y does not change as x changes.
