The slope of the line would be -1/2.
To find the slope we need to make the line in the form y = mx + b:
2x + 4y + 7 = 0
2x + 4y = -7
4y = -2x - 7
÷ 4
y = (-2/4)x - (7/4)
-2/4 simplifies to -1/2.
I hope this helps!
Answer:
A
Step-by-step explanation:
We have to multiply it by two because they have us 2 numbers for the legs, we use the Pythagorean theorem thing, but we have to basically add them, or we can multiply y 2(since they are the same number). Anyways 
Answer:
-6x +10x= 4x
Step-by-step explanation:
-2x(3 - 5x)
-6x +10x= 4x
463 is the answer because-3 m + 4 would equal 463
