Math Problem Statement
Solution
The graph shows the linear equation:
Key components:
- Slope (): This indicates the rate of change of the line. For every increase of 4 units in , increases by 3 units. This is why the line is rising (positive slope).
- Y-intercept (3): The line crosses the y-axis at .
- Positive slope: As indicated in the graph by the word "positive," this means the line is sloping upwards as you move from left to right.
To verify:
- The point where is at , which matches the y-intercept.
- Following the slope , moving 4 units right (in the -direction), you go 3 units up in -direction, confirming the slope.
Would you like a detailed breakdown of how to find the slope or solve similar equations?
Here are 5 questions to explore further:
- How do you calculate the slope between two points on a line?
- What happens to the graph if you change the slope to a negative number?
- How do you determine the x-intercept from a linear equation?
- Can you graph a line given only two points?
- How do parallel and perpendicular lines relate to their slopes?
Tip: The slope is often remembered as "rise over run," where rise corresponds to the change in and run corresponds to the change in .
