Answer:
If it is y=2x-7 the slope is
2
If it is y=-2x-7 the slope is
-2
The y-intercept is -7
Step-by-step explanation:
I don't really know how to give an explanation because the answers are in the equation so I'm sorry for that
Assume (a,b) has a minimum element m.
m is in the interval so a < m < b.
a < m
Adding a to both sides,
2a < a + m
Adding m to both sides of the first inequality,
a + m < 2m
So
2a < a+m < 2m
a < (a+m)/2 < m < b
Since the average (a+m)/2 is in the range (a,b) and less than m, that contradicts our assumption that m is the minimum. So we conclude there is no minimum since given any purported minimum we can always compute something smaller in the range.
