Mr. Perez wants to paint his room for improvement The graph shows
the number of hours y it takes x workers to paint a room.
1. Write a mathematical statement that relates the two quantities
2. Construct a tables of values from the relation
3. How does y change as x increases?
4. Do x and y show direct or inverse variation?
Nonsense= REPORT :)

Answer:
1.it is n=kc
the k is the constant variation
Create a table of values of the equation y = 5x + 2. Create the table and choose a set of x values. Substitute each x value (left side column) into the equation. Evaluate the equation (middle column) to arrive at the y value.
3When the value of x increases, the value of y remains constant. That is, there is no change in y value and the graph is a horizontal line .
4Numerically: Direct Variation: Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases. 6 = k
