Whats the original slope of y-7/12=5/8(x+9)

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.

if x decreases by 4 then y increases by 10
