Hver er jafna línunnar á myndinni hér fyrir neðan?
Select one:
F
y = -1.5x + 3
G
y = 2x - 1.5
H
y = 3x + 2
I
y = 2x + 3
Solution
The equation of the line shown in the graph appears to have a positive slope, crossing the y-axis above the origin.
Looking at the options:
- F) - This equation has a negative slope, so it does not match.
- G) - This equation has a positive slope, but it appears to cross the y-axis at , which does not match the graph.
- H) - This equation has a steep positive slope, but the y-intercept is 2.
- I) - This equation has a positive slope of 2 and crosses the y-axis at 3, which matches the graph.
The correct answer is I) .
Would you like more details on why this is the case?
Here are five questions for further exploration:
- What is the significance of the slope in a linear equation?
- How does changing the y-intercept affect the graph of a line?
- How do you determine the slope of a line from a graph?
- What other forms can linear equations be written in besides slope-intercept form?
- How can you tell if two lines are parallel by looking at their equations?
Tip: The slope of a line represents its steepness, and it can be found by dividing the change in y by the change in x (rise over run).
