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 = - \frac{3}{7} y + \frac{3}{2}a = \frac{3}{2}

6y = - 14x +21

y = \frac{7}{3} x + \frac{7}{2}b = \frac{7}{2}

a + b = 5

ab = \frac{21}{4}

1). 3x + 2y = 6

x = - \frac{2}{3} y + 2 ⇒ a = 2

y = - \frac{3}{2} x + 3 ⇒ b = 3

2). 2x + 3y = 6

x = - \frac{3}{2} y + 3 ⇒ a = 3

y = - \frac{2}{3} x + 2 ⇒ b = 2

4). x + 4y = 4

x = - 4y + 4 ⇒ a = 4

y = - \frac{1}{4} x + 1 ⇒ b = 1
