Number of shares
1050/10=105
After one year share value
10×(1+0.13)=11.3
After the second year share value
11.3×(1−0.05)=10.735
Total
10.735×105=1,127.175

Using the general equation formula;
y-y1=m(x-x1)
y1=20 and x1=4
Since the two lines are perpendicular, they have the same gradients
But gradient for y=4x+5 is 4
Therefore m of the equation is 4
Substituting all this into the general formula;
y-20=4(x-4)
y-20=4x-16
y=4x-16+20
y=4x+4
