Parallel lines have the same gradient.
The equations are either in the form y = mx+b (m is the gradient)
or in general form ax + by + c = 0 (-a/b)
The gradient of y = 2x - 4 is 2.
The answer is B (gradient = -4/-2 = 2)

The recursive formula of h(n) is h(1) = 36 and h(n) = h(n -1) - 5
<h3>How to determine the recursive formula?</h3>
The function is given as:
h(n) = 41- 5n
Calculate h(1) and h(2)
h(1) = 41- 5(1)
h(1) = 36
h(2) = 41- 5(2)
h(2) = 31
Calculate the difference between h(1) and h(2)
d = 31 - 36
d = -5
This means that:
h(1) = 36 and h(n) = h(n -1) - 5
Hence, the recursive formula of h(n) is h(1) = 36 and h(n) = h(n -1) - 5

3/4 equals 15/20, so b+3=15. B=12
