Answer:
No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Barbara buys 3 boxes of eggs costing £1.20 each
1 jar of mayo costing £1.80
2 loaves of bread
she pays £10 note and gets £1.60 change
Barbara works out the cost of 1 loaf of bread as £1.40.
Is she correct? You MUST show your working out.
The explanation of the answer is now given as follows:
Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60
Cost of 1 jar of mayo = £1.80
Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40
Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00
Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50
Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.

Answer:
In the graph we can find two points, lets select:
(2, 15) and (4, 30)
Those are the first two points.
Now, for two pairs (x1, y1) (x2, y2)
The slope of the linear equation y = s*x + b that passes trough those points is:
s = (y2 - y1)/(x2 - x1)
So the slope for our equation is
s = (30 - 15)/(4 - 2) = 15/2
then our linear equation is
y = (15/2)*x + b
now we can find b by imposing that when x = 2, y must be 15 (for the first point we selected)
15 = (15/2)*2 + b = 15 + b
b = 15 - 15 = 0
then our equation is:
y = (15/2)*x
Where we used a division and a multiplication.
