Y = mx + b
slope(m) = -1
(2,-4)...x = 2 and y = -4
now we sub and find b, the y int
-4 = -1(2) + b
-4 = -2 + b
-4 + 2 = b
-2 = b
y = -x - 2
x + y = -2 <== standard form
2.6 is already rounded to the nearest tenth.
If the original answer was 2.67345, it would be rounded to 2.7.
or
if it were 2.63421; it would be 2.6
The number after a decimal; (2.6 is the tenth)
816.45 = hundred
816.45 = ten
816.45 = one
816.45 = tenth
816.45 = hundredth
Answer:
I want to say it's 60...because if you add up 150 and 90 (the right angle) you get 240 which when subtracted from 360 gives you 120...with both E & G being created with equal lengths you would divide 120 by 2 which gives you 60. Hope this helps :)
