Answer:
(-4, 0)
Step-by-step explanation:
The x-intercept is when y = 0

Step-by-step explanation:
Given: It was predicted that it will take 23 minutes to drive to grandma's house but it actually takes 24 minutes.
To find: percent error
Solution:
Predicted time = 23 minutes
Actual time = 24 minutes
Error is the difference between Approximate and Exact Value. Percentage Error is used to compare an estimate value to an exact value.
Error = 24 - 23 = 1 minute
Percent error = (error/actual time) × 100
= 4.167%
