The equation of the line is C. 1X/2 -2
How you figure this out is you first say when x is zero y is what?
y= 1/2 (0) - 2
You would then see that y=-2 (0,-2)
Plot that point
Next you need to find the slope of the line.
Remember slope is rise over run.
When you 'rise' up one (from -2) and 'run' 2
you are now at the point (2,-1) which is on the line.
You can continue doing rise/run along the line to check your answer.
I hope this makes sense! Let me know if you have any questions :)

Answer: 20 percent
The school hall is 60 percent boys and 40 percent girls.
Let x = amount invested at 8%
26000 - x = amount invested at 6%
0.08x + 0.06(26000 - x) = 1860
solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000
Not sure can you explain a little more
