Question

Given the linear equation 3y + 4x = 12, find the y-intercept.

Answer 1

4

Explanation:

3y + 4x = 12

3y = -4x + 12

y = -
`(4)/(3)`x + 4

Answer 2

(0,4)

Explanation:

3y + 4x = 12

To find the y intercept, set x =0 and solve for y

3y = 4*0 =12

3y = 12

Divide by 3

3y/3 = 12/3

y =4
