Answer:
Always
Step-by-step explanation:
The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.
Answer:
-7/10
Step-by-step explanation:
To find the slope of a line, you need to find the 
between two points. I will be using the points (-3, 5) and (7, -2).
= 
= 
= -7/10
so the missing term in the denominator is 7^(-22)
ok done. Thank to me :>
Answer: 3 the actual answer is 2.995421844
