Step-by-step explanation:

principle =Rs 6500

time =2 years

rate =5%

interest =PTR÷100

=6500×2×5÷100

=65000÷100

=650 for first year

principle=6500

time=2 years

rate=6%

interest=PTR÷100

=6500×2×6÷100

=78000÷100

=780 for second year

for first year

amount=P+I

=6500+650

=7150

for 2nd year

amount=P+I

=6500+780

=7280 answer

The point at which a line intersects the x axis is also the point where y=0. Therefore, we can set the equation to 0 and solve it.

$y= \frac{-2}{5}x+12 \\ \frac{-2}{5}x+12=0 \\ \frac{2}{5}x=-12 \\ 2x=-60 \\ \boxed{x=-30}$
Therefore, it intersects the x axis at (-30,0)
