<u>Answer:</u>
4x + 3y = 12
<u>Step-by-step explanation:</u>
At x-intercept, y = 0.
∴ When we substitute y = 0 into the equation, x should equal 3.
• 1st equation: 3x + 4(0) = 12 ⇒ x = 4 ❌
• 2nd equation: 4x + 3(0) = 7 ⇒ x = 7/4 ❌
• 3rd equation: 3x + 4(0) = 7 ⇒ x = 7/3 ❌
• 4th equation: 4x + 3(0) = 12 ⇒ x = 3 ✅
This means the 4th option is the correct one.
To check, we can replace x = 0 into the 4th equation to see if the y-intercept value comes out to be 4:
4(0) + 3y = 12 ⇒ y = 4 ✅
