Find the slop equation.
Slope: -3
Y-intetrcept: -3

Now write it as an inuquality.
It's shaded to the left and the line is not fully filled in. Which means that whatever "y" is, it's Less than the and equal to the slope.

Hope this helps :)
The answer is x=20. Hope this helps.

The first thing we must do for this case is to define variables.
We have then:
x = Tim's age
Now we write the equation:
x + 7 = 3 (x-19)
Answer:
Tim's age in 7 years will be three times what it was 19 years ago:
x + 7 = 3 (x-19)
Answer:
