Answer:99
Step-by-step explanation:
Because the decimal in the tenth placeholder is greater than four you would round up.
To estimate, you can round 627 up to 630 and round 253 down to 250.
650-250=380. 380 is your estimate.
The actual answer is 374.
If the line does not have a y int, then it means it does not cross the y axis....that means it is a vertical line.....its x int is (3,0)...so this equation for the line is x = 3
if the line does not have an x int, it means it does not cross the x axis...that means it is a horizontal line...its y int is (0,-4)...so the equation for this line is
y = -4
