Jay wrote an equation to determine sales tax on an item he wanted to buy. The equation was Y equals 0.0 9X, where Y represents t
mixas84 [53]

Step-by-step explanation:

Given the equation:

y = 0.09x where:

  • x: represents the cost of the item before tax is added.
  • y: represents the amount of sales

=> On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars)

We create a table of values

x    y

0   0

10  0.9

=> the line go through two points (0, 0) and (10, 0.9)

Hence tow dwaw a graph, we just connect two points together.

Please have a look at the attached photo.
