Answer:
B
Step-by-step explanation:
when x is 0 y=4(0)+12 y=12
y is 0 y=4(-3) +12 = 12=12
Answer:
see graph
Step-by-step explanation:
Personally I put into slope intercept form before graphing
y - 3 = 1/2 (x+2)
y -3 = 1/2x + 1
y = 1/2x + 4
4 is y-intercept
1/2 is slope. 
The point can be found as the weighted average of the given points, with the weights being the reverse of the line segment ratio values. The dividing point D will be
... D = (3*(4, 8) + 1*(14, 10))/(3 + 1) = (12+14, 24+10)/4
... D = (6 1/2, 8 1/2) . . . . . matches your second selection
14. (n-5)*4+7
15. No, this would not be neccesary because if I were to distribute 1/2 to both 4 and 6, I know that I would get half of those numbers which would give me 2x+3. I also know that if I distribute 1/3 to both 9 and 24, I would get 1/3 of each number which would be 3 and 8.
X=10 because 76-26=50 and 50/5=10, z=104 because 180-76=104
