The y-intercept means that Karma was given $60 for her birthday. Therefore, option C is the correct answer.
The given equation that models the given situation is y=75x+60.
What is the y-intercept?
The y-intercept of a graph is the point where the graph intersects the y-axis.
We know that the x-coordinate of any point on the y-axis is 0. So the x-coordinate of a y-intercept is 0.
Now, Graph the line using the slope and y-intercept, or two points.
Slope: 75
y-intercept: (0, 60)
The coordinates to plot the graph is (0, 60) and (1, 135).
Here, in the graph, if we then look at the y-intercept we can see that the function crosses the y-axis at a value of 60.
Therefore we can safely say that the y-intercept means that Karma was given $60 for her birthday.
The y-intercept means that Karma was given $60 for her birthday.
Therefore, option C is the correct answer.
