Answer:
5
Explanation:
First you need to know the SLOPE INTERCEPT FORM: y = mx + b
where m is the slope, and be is the y intercept
Now we re-write your question in the slope intercept form
Slope- Intercept form of 3y + 4x = 15: y = -4/3x + 5
according to the slope intercept form (y = mx + b) ~ the y intercept is 5
Dont get why? well the slope intercept form says y= mx + b, once we had re-written your equation as -4/3 + 5 in this case the b (y-intercept) is +5
