**Answer:**

£65

**Step-by-step explanation:**

We have a line passing through 3 points. We can use the first

two points to find the equation of the line.

(6,3), (8,4)

slope m = (4-3)/(8-6) = 1/2

We can use the point slope form y-y1 = m(x-x1) or

the slope intercept form y = mx + b

to find the equation of the line.

Let's take the point (6,3) and use y = mx + b to find b

y = 3, x = 6, m = 1/2

3 = (1/2)(6) + b

3 = 3 + b

0 = b

The equation of our line is y = (1/2)x

We have a line of equation y = (1/2)x going through point (n,-2)

Plugging in we have: -2 = (1/2)n

2(-2) = n

-4 = n

Your answer is n = -4

NOTE: looking at the 3 points as given initially: (6,3), (8,4), (n,-2)

We can see that 3 = (1/2)6 and 4 = (1/2)8 so -2 = (1/2)n makes sense

Hope this helps you :)

**Answer:**

33 3/4

**Step-by-step explanation:**

L*W*H=Volume

1 1/2*4 1/2=6 3/4

6 3/4*5=33 3/4

**Answer:**

13/12

**Step-by-step explanation:**

B - 7/4 = -2/3

B = -2/3 + 7/4

B = 13/12
