Answer:
28, 29, and 30
Step-by-step explanation:
There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.
The answer is 9, you have to add them together which equals 9.
Y=-1/4+4
-1/4 is the slope and the 4 is the y-intercept (where the line touches the y-axis)
I hoped this help's!!!
