The four solutions of the given function are:
{(8 , 28) , (–6 , –28) , (1 , 0) , (–2 , –12)} ⇒ answer A
Step-by-step explanation:
To find the a solution of a linear function
1. Substitute x and y of the function by the coordinates of the solution
2. Calculate the two sides of the function
3. If the value of the left hand side (L.H.S) is equal the value of the
right hand side (R.H.S), then the ordered pair is a solution of
the function
∵ 4 x - y = 4
∵ The coordinates of the ordered pair are (8 , 28)
- Substitute x by 8 and y by 28 in the L.H.S
∴ L.H.S = 4(8) - (28) = 32 - 28 = 4
∵ R.H.S = 4
∴ L.H.S = R.H.S
∴ (8 , 28) is a solution of the function
∵ The coordinates of the ordered pair are (-6 , -28)
- Substitute x by -6 and y by -28 in the L.H.S
∴ L.H.S = 4(-6) - (-28) = -24 + 28 = 4
∵ R.H.S = 4
∴ L.H.S = R.H.S
∴ (-6 , -28) is a solution of the function
∵ The coordinates of the ordered pair are (1 , 0)
- Substitute x by 1 and y by 0 in the L.H.S
∴ L.H.S = 4(1) - (0) = 4 - 0 = 4
∵ R.H.S = 4
∴ L.H.S = R.H.S
∴ (1 , 0) is a solution of the function
∵ The coordinates of the ordered pair are (-2 , -12)
- Substitute x by -2 and y by -12 in the L.H.S
∴ L.H.S = 4(-2) - (-12) = -8 + 12 = 4
∵ R.H.S = 4
∴ L.H.S = R.H.S
∴ (-2 , -12) is a solution of the function
The four solutions of the given function are:
{(8 , 28) , (–6 , –28) , (1 , 0) , (–2 , –12)}
