Answer:
m = -1/3
Step-by-step explanation:
The slope of the line can be calculated using the slope formula.

Since this is the line with points AB, the slope of any line perpendicular to it will be -1/3. All perpendicular lines cross at a 90 degree angle and as such their slopes are the negative reciprocals of each other. This means 3 becomes -1/3.
Answer:
Step-by-step explanation:
804.25mm
2.8 mi
3.3mi
4.8+7(3)=8+21=29mi
5.yes, she hikes continuously so distance can be fractional parts of a mile
7.y=12x+120, y=12(5)+120=180
8.y=6.5x+10,6.5(10)+10=75
-250 feet, because you are 250 feet below sea level.
Answer:
the answer is 800
Step-by-step explanation:
you have 4,000 lets make it smaller.
