(a)
Graph the data.
(a)
Answer to Problem 45SGR
Explanation of Solution
Given:
The table shows the cost of picking your own strawberries at a farm
Concept Used:
The x -intercepts are where the graph crosses the x -axis, and the y -intercepts are where the graph crosses the y -axis.
Then, algebraically,
- an x -intercept is a point on the graph where y is zero, and
- a y -intercept is a point on the graph where x is zero.
More specifically,
- an x -intercept is a point in the equation where the y -value is zero, and
- a y -intercept is a point in the equation where the x -value is zero.
Calculation:
In order to plot the points in graph we take all points from the table. The points are
