Question

Determine the y- intercept of 3x+2y=9

Answer 1

`\boxed{(0 , 4.5)}`

Explanation:

→ Rearrange into y = mx + c format

2y = - 3x + 9

→ Divide everything by 2

y = -1.5x + 4.5

→ Substitute x = 0

y = 0 + 4.5 ⇒ 4.5

Answer 2

The y intercept is (0,4.5)

Explanation:

Because the y-intercept occurs at x = 0, we can substitute this into our equation and solve for y.

3(0) +2y = 9

2y = 9

y=4.5
