Question

Determine the slope of 3x-4y=12

Answer 1

3x-4y=12

y=mx+b

slope is also m

b= y-intercept

move 3x to the other side

sign changes from +3x to -3x

3x-3x-4y=-3x+12

-4y=-3x+12

divide both sides by -4

-4y/-4=-3/-4+12/-4

Cross out -4 and -4, divide by 4 and then becomes -1*-1*y=y

12/-4=-3

y=3/4x-3

Answer: slope is 3/4

Answer 2

Answer:

3/4

Step-by-step explanation:

the slope is 3/4 and the y intercept is -3 hope this helps (-:
