Answer:
400.5 miles
Step-by-step explanation:
227.5 + 173=400.5
Combine like terms so 12b=12b
Then divide by 12 which then b=1
The answer is -1/4
Perpendicular means opposite slope in this type of question
Answer:
The answer should be -124.
So, you need to know that the slope stays where it is, and that the 6 is not part of the final answer, so get rid of it.
y=2x+b
Now, submit x in for x, and y in for y.
3=2(1)+b
3=2+b
1=b
Put this in for the equation missing the b,
y=2x+1
Now check it; if you put 1 in for x, does y=3?
