Answer:
-3
Step-by-step explanation:
To find out what the y-intercept is, we must first put the equation into slope-intercept form: y = mx + b. (M is the slope & b is the y-intercept)
3x-4y=12
(3x-3x) - 4y = 12 - 3x
-4y = 12 - 3x
-4y = -3x + 12
-4y/-4 = -3x + (12/-4)
Y = -3x + (-3) or y = -3x -3
Hope this helps!
