I have the following math problem:

Write the equation of the line in the standard form. Containing

**(9,8)**and**perpendicular**to 3x-4y-5=0.I am so lost! I have no idea where to begin.

Also, previously I had asked the following question:

Find an equation of the line containing the given points (1,3) and -3,-7). Express your answer in slope-intercept form.

Very nice tutors on this site helped me with this problem and I watched some videos that were helpful. Here's what I came up with as my answer:

**y=2.5x+.5**

Did I totally butcher this problem? Did I do it right or am I completely off? Please help
