The answer would be irrational
Answer:
see explanation
Step-by-step explanation:
4x + 10 = 2y - 4x ( add 4x to both sides )
8x + 10 = 2y , that is
2y = 8x + 10 ( divide through by 2 )
y = 4x + 5
then
x = 2 : y = 4(2) + 5 = 8 + 5 = 13
x = 4 : y = 4(4) + 5 = 16 + 5 = 21
x = - 1 : y = 4(- 1) + 5 = 1
so table is
x y
-----------
2 13
4 21
- 1 1
The y intercept is zero because it crosses the y axis at 0
Both values need to be in the same usable form. So, I would convert the two values into minutes. That leaves you 10 minutes of video games and 60 minutes of television. This ratio would be 10/60 or 10:60. Simplified would be 1/6 or 1:6.
Y = -2x + b
Plug in the point
1 = -2(-3) + b
1 = 6 + b, b = -5
Solution: y = -2x - 5
