Question 17281: what is the equation of the line passing through (0,15) perpendicular to the graph of y=-3/4x+2/3???
thanks.

You can put this solution on YOUR website! This is going to be easier than most problems to find the equation of a line. First, you are given the equation of a line  . The slope of this line is the coefficient of x, which is  . The slope of ANY line parallel to this line is ALSO (no extra charge for that one!!), and the slope of ANY line that is PERPENDICULAR to this line is the NEGATIVE RECIPROCAL of this slope, which would be  .
Now, if the line passes through (0,15), then the y-intercept is 15. The final answer for this problem is in the form  , where b is the y-intercept, which is  , and m is the slope which is .
Final answer: 
R^2 at SCC
