Read each question carefully and answer to the best of your ability. Show all your work for short answer questions.
1. What does the slope of a linear graph represent?
The starting value of the dependent variable
The change in the dependent variable for every unit change in the independent variable
The point where the graph crosses the x-axis
The total value of the independent variable
2. In the equation y = mx + b, what does 'b' represent?
The slope of the line
The x-intercept
The y-intercept
The origin
3. A horizontal line has a slope of .
4. The y-intercept is the point where the line crosses the axis.
5. A graph shows the distance a car travels over time. If the line is steeper, what does that indicate about the car's speed?
6. Describe a real-world scenario that could be represented by a linear graph with a negative slope.
7. A line with a positive slope goes downwards from left to right.
True
False
8. The y-intercept always represents the initial value or starting point.
True
False
