m = 5/8
Step-by-step explanation:
y-7/12=5/8 (x+9) represents a linear equation whose slope we want to determine.
Clear this y-7/12=5/8 (x+9) of fractions by finding the LCD (it is 72) and multiplying each term by it:
72[y - 7/12 = (5/8) (x+9)
We obtain 72y - 42 = 45 (x+9).
Perform the indicated mult.: 72y - 42 = 45x + 405.
Solving for y, we get 72y = 45x + 405 + 42, or 72y = 45x + 447.
Dividing boh sides by 72 to isolate y, we get y = (45/72) x + 447/72.
The slope of this straight line is 45/72, which can be reduced to m = 5/8.
