Directions: Using the digits 1 through 9, at most one time each, fill in the boxes to create a linear equation that has an x- and y-intercept with integer values.

### Hint

### Hint

When finding an x – intercept, how does the coefficient of the x-variable operate with the constant value?

When finding a y-intercept, how does the coefficient of the y-variable operate with the constant value?

### Answer

### Answer

There are many possible solutions:

Example:

2x + 3y =6

1x + 4y = 8

3x + y =9

Lol. I thought the instructions were to use *all* the digits, 1–9. I recalled that 123456789 is divisible by 3, so with a little thought realized this would work:

3x + 6y = 1457892

Maybe a challenge question?

Well now that’s an interesting twist. Thanks for sharing that!
