What is Slope?
Before diving into exercises, let's clarify what slope is. The slope of a line measures the steepness and direction of the line. It is calculated as the rise (change in y) over the run (change in x). The formula for calculating slope (m) is given by:
[ m = \frac{y_2 - y_1}{x_2 - x_1} ]
Where:
- ( m ) = slope
- ( (x_1, y_1) ) and ( (x_2, y_2) ) are two points on the line.
Types of Slope
- Positive Slope: When the line rises from left to right. (e.g., m > 0)
- Negative Slope: When the line falls from left to right. (e.g., m < 0)
- Zero Slope: A horizontal line where there is no change in y-value. (e.g., m = 0)
- Undefined Slope: A vertical line where there is no change in x-value. (e.g., m is undefined)
Understanding these types is crucial for interpreting graphs and equations.

Answers to the Worksheet
To assist with self-assessment, below are the answers to the worksheet problems.
-
Slope: ( m = \frac{7 - 3}{4 - 2} = \frac{4}{2} = 2 ) 📏
-
Slope: From y = mx + b format, slope ( m = 2 ).
-
Slope: Undefined (vertical line).
-
Slope: ( m = \frac{-1 - (-4)}{6 - 3} = \frac{3}{3} = 1 ) 📊
-
Slope: ( m = \frac{9 - 0}{3 - 0} = 3 ).
-
Slope: Rearranging 4x - 2y = 8 to y = 2x - 4 gives slope ( m = 2 ).
-
Slope: ( m = \frac{-6 - 3}{2 - (-1)} = \frac{-9}{3} = -3 ).
-
Equation: Using point-slope form ( y - y_1 = m(x - x_1) ): [ y - 5 = -3(x - 2) ] Simplifying gives ( y = -3x + 11 ).
