Answer:
y = 1/2x - 2
Step-by-step explanation:
use formula y = mx + c
m = gradient
c = y intercept
x = 8, y = 6
2x + 5y = 46______(1)
3x - 2y = 12_______(2)
(1) x 3 --> 6x + 15y = 138
(2) x 2 --> 6x -4y = 24
(1) - (2) --> 19y = 114
y = 6 sub into (2)
3x - (2 x 6) = 12
3x = 24
x = 8
114
23 × 5 = 100 + 15 = 115
2 + 115 - 3 = 2 + 112 = 114
10 2 28
9 3 30
8 4 32
7 5 34
6 6 36
