Replace x with -2 and solve:
A) -2 + -2 = -4 which is not less than or equal to -8
B) 2 + -2 = 0, this is greater than or equal to -8
C) -2 + -2 = -4, this is not less than -8
D) 2 + -2 = 0, this is not greater than 8
Answer: B is true
The y-intercept of
and the y-intercept of
are equal
The equations are given as:
![2y = 3x - 4](https://tex.z-dn.net/?f=2y%20%3D%203x%20-%204)
![4x - 2y=4](https://tex.z-dn.net/?f=4x%20-%202y%3D4)
Make y the subject in both equations
<u>First equation</u>
![2y = 3x - 4](https://tex.z-dn.net/?f=2y%20%3D%203x%20-%204)
![y = \frac 32x - 2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%2032x%20-%202)
<u>Second equation</u>
![4x - 2y=4](https://tex.z-dn.net/?f=4x%20-%202y%3D4)
![y = 2x - 2](https://tex.z-dn.net/?f=y%20%3D%202x%20-%202)
A linear equation is represented as:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where b represents the y-intercept
So: By comparison,
--- the y-intercept of the first equation
--- the y-intercept of the second equation
2 = 2.
Hence, the y-intercept of
and the y-intercept of
are equal
