Step-by-step explanation:
please can u write question properly I will help u as like a brother
Given : table?
x y
–5,14
–2,11
1,8
4,5
To Find : equation of the linear function represented by the table
Solution:
x y
–5 14
–2 11
1 8
4 5
Slope = (5 - 8) / ( 4 - 1) = -3/3 = - 1
y - 5 = - 1(x - 4)
=> y - 5 = -x + 4
=> x + y = 9
x + y = 9 is the equation of the linear function represented by the table
Verification
x y x + y
–5 14 9
–2 11 9
1 8 9
4 5 9
