Front

What is the vertical axis on a coordinate plane?

Back

The y-axis, which runs up and down.

Front

Which quadrant contains the point (2, 5)?

Back

Quadrant I.

Front

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

Back

Use the formula: slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line that passes through (-1, 5) and (0, -9)?

Back

-14.

Front

What is the slope of the equation y = 2x - 1?

Back

2.

Front

Define the term 'origin' in a coordinate plane.

Back

The point (0, 0) where the x-axis and y-axis intersect.

Front

What are quadrants in a coordinate plane?

Back

The four sections created by the x-axis and y-axis.

Front

What is the formula for the slope-intercept form of a line?

Back

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.
