At what point is $y=5x+965$ to the graph of $y=2x^3-3x^2-247x-7$? Here is the question:

The line $y=5x+965$ is tangent to the graph of $y=2x^3-3x^2-247x-7$ at the point...?

Anytime I am trying to plot the graph I end up with a line that's basically attached to the $y$-axis.
Can anyone help?

Alternative answer is that you can consider the line y=5x+965 on the form y=kx+m 
where k is = 5. 
Then the derivative of $f(x)=2x^3-3x^2-247x-7$ needs to also be 5 in that point.
This means you can set $f'(x)=5 $ and get $6x^2-6x-252=0\Leftrightarrow x_1=-6$ $,x_2=7$
Then you can find f(-6) and f(7). The equation for a tangentline in a point is:
$y-y_1 = k(x-x_1)$ which gives $y=5(x-(-6))+f(-6)$ which is your tangentline.
$y=5(x-7)+f(7)$ is a parallell line to y = 5x+965. with the equation y = 5x -1232
