Find the equation of a line with the given information:
f(2)=8\displaystyle {f{{\left(-{2}\right)}}}=-{8} and f(9)=14\displaystyle {f{{\left({9}\right)}}}={14}.

Write your answer in point-slope form. If your answer is a vertical line, type your answer as `x=#`, and if your answer is a horizontal line, type your answer as `y=#`.
 

Write your answer in slope-intercept form. If your answer is a vertical line, type your answer as `x=#`, and if your answer is a horizontal line, type your answer as `y=#`.
