Algebra 1 warm up 12/4 & 12/5

Front

What is the definition of slope in a linear equation?

Back

Slope is a measure of the steepness of a line, represented as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What are the types of slope?

Back

1. Positive Slope: Line rises from left to right. 2. Negative Slope: Line falls from left to right. 3. Zero Slope: Horizontal line, no rise. 4. Undefined Slope: Vertical line, no run.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line where the x-value remains constant, and the y-value can change.

Front

What does a zero slope indicate about a line?

Back

A zero slope indicates a horizontal line where the y-value remains constant, and the x-value can change.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)
