Coordinate Plane and Slope Review

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point on the coordinate plane, written in the form (x, y).

Front

How do you express the numbers (-2, 3), (-1, 4), (0, 5), (1, 6) as ordered pairs?

Back

The ordered pairs are (-2, 3), (-1, 4), (0, 5), (1, 6).

Front

What is the formula to find the slope of a line?

Back

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

Front

Find the slope of the line that passes through the points (1, 2) and (3, 4).

Back

The slope is 1.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.

Front

What is the slope of the line represented by the equation 3y = 9x + 18?

Back

The slope (m) is 3.

Front

What is the y-intercept in the equation of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form y = mx + b.

Front

In the equation y = 2x + 1, what is the slope?

Back

The slope is 2.

Front

In which quadrant does the point (-2, -3) lie?

Back

The point (-2, -3) lies in Quadrant III.

Front

What are the coordinates of the origin in the coordinate plane?

Back

The coordinates of the origin are (0, 0).
