STAAR Review Algebra I

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never intersect. They have the same slope.

Front

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through the points (2, 4) and (6, 12)?

Back

The slope is 2.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

What is the maximum point on a parabola?

Back

The maximum point on a parabola is the highest point on the curve.

Front

What is the minimum point on a parabola?

Back

The minimum point on a parabola is the lowest point on the curve.

Front

What are the roots of a quadratic equation?

Back

The roots are the values of x where the parabola intersects the x-axis.

Front

What is the y-intercept of a line?

Back

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

Front

What is the difference between the slope of a line and its y-intercept?

Back

The slope indicates the steepness of the line, while the y-intercept indicates where the line crosses the y-axis.
