Question

Which statement could be an interpretation of the graph’s x-intercept or y-intercept?

On a coordinate plane, a line goes through points (0, 800) and (400, 0).
Ayita opened a bank account with $800.
Eight hundred employees of a company made a total of 400 calls.
Kele added $200 to his bank account every 2 weeks.
Maria was able to travel 400 miles in 4 days.

Answer 1

The y-intercept of a graph represents the value of y when x is zero. In this case, it is the point where the line intersects the y-axis. In the given graph, the y-intercept is (0, 800), indicating that the line starts at y = 800.

Step-by-step explanation:

The y-intercept, a, of the line describes where the plot line crosses the y-axis.

The y-intercept of the best-fit line tells us the best value of the relationship when x is zero. In some cases, it does not make sense to figure out what y is when x = 0.

For example, in the third exam vs. final exam example, the y-intercept occurs when the third exam score, or x, is zero.

Since all the scores are grouped around a passing grade, there is no need to figure out what the final exam score, or y, would be when the third exam was zero.

The y-intercept, a, of the line describes where the plot line crosses the y-axis.

The y-intercept of a line is represented by the value of the y-coordinate when x = 0.

In the given graph, the y-intercept occurs at the point (0, 800), which means that the line intersects the y-axis at y = 800.

The b in the equation y = mx + b represents the y-intercept, which is the point where the line intersects the y-axis.

In the given graph, the y-intercept is represented by the point (0, 800), indicating that the line starts at y = 800.
