Slope form M=y2-y1/x2-x2 M= -7 -(-1)/-1-3 M= -6/-4 M=3/2  So 3/2 is your slope   Now  use one if the pair points (3,-1) and slope to find b. -1=2/3(3)+b -1=2+b -1-2=b -3=b  Y=2/3x-3

-1 - (-7) over 3 - (-1) = M

-1 + 7 over 3 + 1 = M

6 over 4 = M

6/4 = M

3/2 = M

Solve for x and y 9/x-4/y=8
borishaifa [10]
You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.

Solving for x:  </span><span>9/x-4/y=8       Mult all 3 terms by xy to eliminate the fractions.

9(xy)/x - 4xy/y = 8xy         =>       9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)

                                                                        then 9y = x [ 4(1+2y) ]
                                                                                     9y
                                                            therefore x = ------------
                                                                                  4(1+2y)

Solve for y using a similar approach.
