Answer:
£8.10
Step-by-step explanation:
Divide £10.80 by 4 to find the cost of 1 Kg, then multiply this by 3
£10.80 ÷ 4 = £2.70 ← cost of 1 Kg , then
cost of 3 Kg = 3 × £2.70 = £8.10
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.

3-2=1 therefore it should be 1/7 the third answer. Hope that helps
Answer:
A. the slope value is 1/4
B. 0
C. y = 1/4x
Step-by-step explanation:
A: the slope can be calculated with the formula

m is the slope
(x1, y1) is your first coordinate point (any point will work)
(x2, y2) is your second coordinate point (any point will work)
Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:

B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.
C:
the equation of the graph is y = mx + b.
m is the slope = 1/4
b is the y-intercept = 0
Therefore the equation is y = 1/4x
