Answer:
(3). 14x + 6y = 21
Step-by-step explanation:
(3) will be my first educational guess :) therefore, analyze x- and y- intercepts I would start from
3). 14x + 6y = 21
Solve for "x" to find x-intercept and for "y" to find y-intercept.
14x = - 6y + 21
x = - y + ⇒ a =
6y = - 14x +21
y = x + ⇒ b =
a + b = 5
ab =
1). 3x + 2y = 6
x = - y + 2 ⇒ a = 2
y = - x + 3 ⇒ b = 3
2). 2x + 3y = 6
x = - y + 3 ⇒ a = 3
y = - x + 2 ⇒ b = 2
4). x + 4y = 4
x = - 4y + 4 ⇒ a = 4
y = - x + 1 ⇒ b = 1
