What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

How do you find the slope between the points (2, 5) and (-3, 5)?

Back

The slope is 0 because the y-coordinates are the same.

Front

What is the slope of the line that passes through the points (1, 2) and (4, 5)?

Back

The slope is \frac{5 - 2}{4 - 1} = \frac{3}{3} = 1.

How do you identify the coordinates of a point on the coordinate plane?

Back

Coordinates are given in the form (x, y), where x is the horizontal position and y is the vertical position.

What is the significance of the slope in a real-world context?

Back

The slope represents the rate of change between two variables.

What does it mean if the slope is positive?

Back

As x increases, y also increases.
