Answer:
Step-by-step explanation:
a) Mark any two points in line a
(0,7) ; (5,-3)
Find the slope
slope = y2 - y1 /x2-x1

Equation: y-y1 = m(x-x1)
y - 7 = -2(x - 0)
y - 7 = -2x
y = -2x + 7 --------> line a
c) equation of line b
(2,-1); slope = -2 {as b line is parallel to line a}
y - y1 =m(x-x1)
y -(-1) = -2*(x - 2)
y + 1 = -2x - 2*-2
y + 1 = -2x + 2
y = -2x + 2 -1
y = -2x +1 ------> equation of line b

(Ms)Kisha is correct.
How?
Well, I figured this out by using common sense. 8 mangoes are 10 dollars. Since the price is higher than the amount, so it has to be at least more than one.
We could write more ratios. You can always write more ratios. You just multiply/divide both sides. Examples below:
2:5
16:20
