Question

Which graph below represents the equation 3x + 4y = 12?

Answer 1

Graph A

EXPLANATION :

From the problem, we have the equation :

`3x+4y=12`

Get the x and y-intercepts :

Let x = 0,

3(0) + 4y = 12

4y = 12

y = 12/4

y = 3

The y-intercept is (0, 3)

Let y = 0

3x + 4(0) = 12

3x = 12

x = 12/3

x = 4

The x-intercept is (4, 0)

The option that a line intersects the x-axis at (4, 0) and the y-axis at (0, 3) is graph A
