Find the x-intercept and the y-intercept of 2x + 6y =24
viktelen [127]

Answer:

x-intercept = 12, y-intercept = 4

Step-by-step explanation:

<u>Substitute 0 into x:</u>

2(0) + 6y = 24

6y = 24

<u>Divide each side by 6:</u>

y = 4

<u>Substitute 0 into y:</u>

2x + 6(0) = 24

2x = 24

<u>Divide each side by 2:</u>

x = 12
