Alg 1: Locating points, slope-using/not using graph

Front

What is the formula for calculating the slope between two points?

Back

m = \frac{y_2 - y_1}{x_2 - x_1}

Front

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 a vertical line?

Back

Undefined.

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.

Front

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.

Front

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

Back

The slope represents the rate of change between two variables.

Front

What does it mean if the slope is positive?

Back

As x increases, y also increases.

Front

What does it mean if the slope is negative?

Back

As x increases, y decreases.

Front

How can you determine the location of Point A (4, 7) on a coordinate plane?

Back

Move 4 units right and 7 units up from the origin.
