What is the slope of the line 12y-9x=25?
-9
3/4
4/3
25/12
9
2 answers:
The slope of the line would be 3/4.
First, you would convert the equation into slope intercept form. To do this, you would add 9x to both sides of the equation (as shown below).
12y-9x=25
+9x +9x
____________
12y=9x+25
(we cannot directly add 9x and 25 because they are not like terms)
next, you would divide both sides by 12 (as shown below).
12y=9x+25
__ ______
12 12
__________
Y= 9/12×+25/12
y= 3/4x+2.08
(12 and 12 cancel each other out when divided by each other.)
(3/4 is just the simplified version of 9/12)
Answer:
3/4
Step-by-step explanation:
12y-9x=25
We need to get y alone so the equation is in the form
y= mx +b where m is the slope and b is the y intercept
12y-9x=25
Add 9x to each side
12y-9x+9x=9x+25
12y = 9x+25
Divide by 12
12y/12 = 9x/12 +25/12
y = 3/4x +25/12
The slope is 3/4 and the y intercept is 25/12
