doesn't make any sense, so I figure you either meant +2 and you failed to hold the shift key when you pressed the +/= key, or you meant -2 and you simply pressed the +/= key instead of the _/- key. Either scenario being equally likely, I'm going to do the problem for the following function:
Where is an arbitrary real number constant.
The minimum slope tangent to the original function will occur at the point where the first derivative has a minimum.
Which has a zero at
For the original function
Hence, the point of tangency is
So you want an equation of a line that passes through the point with a slope of 2.
Once you figure out whether or ,
Then you can complete the problem.
By the way, the question was also worded incorrectly in the first place. You cannot find THE equation of a line. You can only find AN equation of a line.
