Answer:

$y + 4 = -\frac{5}{6}(x - 8)$

Step-by-step explanation:

In the Point-Slope Formula, $y - y_1 = m(x - x_1),$ all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

Show how to get answer to... 3/4+9/6 =

svet-max [94.6K]

The answer for your question is 2.25 (decimal), or 2 1/4.

I got this answer by changing both 3/4 to 9/6, which 3/4 = 0.75, and 9/6 = 1.50.

Now, you add both 0.75 and 1.50 together, which gives you 2.25, which is the answer that I got.

Hope this helped!
