Answer:
y=2x-1
Step-by-step explanation:
Gradient : (7-3) / (4-2) = 2
y=2x+c
substitute one of the points
3=2*2+c
c=-1
y=2x-1

8/3=2.67
2.67>2.5
Answer: 500 investigated @ 12%, 1,000 @ 13%, 1,500 @ 14%.
Process:
Suppose $x investigated at 12%, $y @ 13%, $(x+y) @ 14%.
According to the question we can set up the equations:
x+y+x+y=3000
0.12x+0.13y+0.14(x+y)=400
Solve it: x=500, y=1,000.
So x+y=1,500.
