Question

Jay wrote an equation to determine the sales tax on an item he wanted to buy. The equation was y = 0.09 x, where y represents the amount of sales tax and x represents the cost of the item before tax is added. Which graph represents this information?

Sales Tax Amounts
On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars). A line goes through (10, 0.9).

Sales Tax Amounts
On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars). A line goes through (1, 10).

Sales Tax Amounts
On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars). A line goes through (30, 1).

Sales Tax Amounts
On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars). A line goes through (1, 30).

Answer 2

(A)On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars). A line goes through (10, 0.9).

Explanation:

Jay's equation was y=0.09x, where y represents the amount of sales tax and x represents the cost of the item before tax is added.

The graph which represents the information is the pair which satisfies the given equation.

`\text{In Option A with point (10, 0.9), If x=10, y=0.09X10=0.9}\\$In Option B with point (1, 10), If x=1, y=0.09X1=0.9\\eq 10\\$In Option C with point (30, 1), If x=30, y=0.09X30=2.7\\eq 1\\$In Option D with point (1, 30), If x=1, y=0.09X1=0.9\\eq 30`

Therefore, only option A satisfies the given equation.
