" e+7 " means the same thing as " x 10⁷ ".
They both mean "move the decimal point 7 places that way ===> ."
So take the 3.82 and do that to it.
If there aren't enough places to move the decimal point far enough,
then add some zeros onto the end of the 3.82 before you move
the point.
I think it's 24/30 but don't quote me on it.
It is 20 if you plug in 5 for k
Use the point-slope formula
y-y1=m(x-x1)
y-1=-3(x-1)
y-1=-3x+3
y=-3x+4
The rise should be -3 and the run should be 2, the line should also pass through 7.
