Question

8. Find the y-intercept for the equation
3y + 4x = 15

Answer 1

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
