Question

Melinda works at a cafe. Each day that she works, she records x, the total dollar amount of her customers’ bills and then y, her total daily wages. The table shows her data for 2 weeks.
According to the line of best fit, what is the minimum amount, to the nearest dollar, Melinda will earn for each day of work, even if she serves no customers?

$18
$26
$36
$40

Answer 1

We have been given a graph in which, x-axis represents the total dollar amount of bills of Melinda's customers and y-axis represents Melinda's total daily wages.

Since we know at y-intercept x equals zero. We can see that our line of best fit crosses y-axis at 26; so at y equals 26, x (bills of Melinda's customers) will be zero.

Therefore, according to the line of best fit Melinda will earn the minimum amount of $26 even if she serves no customers.    

Answer 2

$26 is the answer :)
