10. 8x+4y=4. y=mx+b
-8x. -8x
4y=-8x+4
÷4. ÷4. ÷4
y = -2x +1
slope = -2. y-int= 1
11. slope is changing y over changing x
m = (y2 -y1)/(x2-x1) (0,-1) x1 = 0, y1=-1
(-4-(-1))/(-2-0) (-2,-4) x2 = -2, y2 = -4
(-4 + 1) / (-2)
-3/-2 = 3/2 answer is 3/2
12. b because negative cause it flip in x axis and it become flatter because of the fraction.
13. 2y =8-8x
÷2. ÷2 ÷2
y = 4 - 4x
Answer A
14. B
Answer:
A, B, D, E
Step-by-step explanation:
To find if something is equal to fifty percent, split the second number in half.
For example, lets use option D.
32/2=16
16 is the first number in the option, meaning it is 50%.
Lets use an example where it wouldn't work. In this case, option C.
12/2=6
6≠9
Meaning 9 is not 50% of 12.
