Question

What is the y-intercept of the line with the equation 3x + 4y = 12? A) 4 B) 3 C) 2 D) 1 3

Answer 1

Answer:

B) 3

Step-by-step explanation:

3x+4y=12 is actually y=-3/4+3

the +3 part is the y intercept

Answer 2

Answer:

Option B, 3

Step-by-step explanation:

Step 1: Convert this into y = mx + b form

3x + 4y - 3x = 12 - 3x

4y / 4 = (-3x + 12) / 4

y = -3/4x + 3

Step 2: Determine the y-int

y = mx + b

m is slope

b is y-int

y = -3/4x + 3

b is 3 which means that the correct answer is Option B, 3

Answer:  Option B, 3
