Question

# Use the function Y = 1.5X + 3 to complete the table of values.

X | ||||

Y | 9 | 6 | 0 | -3 |

Hint:

### To complete the table, we need to calculate the value of x corresponding to the value of y according to given equation. First we will convert the equation ‘in terms of y’ so that it is easy to calculate the values of x for every y. Then we put the value of x which we found in the table.

## The correct answer is: -4

*Step by step solution:*

The given equation is

Y = 1.5x + 3

We rewrite this equation with ‘x’ on one side of the equation so that it is easy to find its value.

Using , we get

Now, we calculate x for the given values of y.

Putting y = 9, in the above equation, we get,

Similarly, putting y = 6 in the above equation,

Putting y = 0 in the above equation,

Finally, putting y = -3, we get

Thus, we complete the table as

X

4

2

-2

-4

y

9

6

0

-3

We should always try to rewrite the equation in terms of the variable whose value is given so that it is easy to find the value of the required variable. Then we just need to calculate the values carefully.
