Its the 2nd one becuase 2(-1)+2=0 witch is greater than -4.
2x - 4y = 10
7x - 9y = 12
_________
9x - 5y = 2
Answer:
This is Conplementary and adjacent
Step-by-step explanation: Complementary means they add up to 90 degrees and they are right next to each other
Answer: slope is 0
to find the slope , you have to subtract y-es and divide them by x-es.(delta y/ delta x)
so,
(-6,-2) (-7,-2)
slope: -2-(-2)/-7-(-6)
slope:0/ -1
slope: 0
which looks on the graph like this:
Variable
