Step-by-step explanation:
7p – 3q
if p= 8 and q = -5
7(8)-3(-5)
56+15
=71
Place a dot on the origin.
A line that has a slope of

goes by this formula:

So "rise -2" and "run 3."
Rise -2 is basically go down 2, so go down 2 units from the origin. Run 3 means go right 3 units from (0, -2).
Draw a line through (3, -2) and (0, 0).

<em>1</em><em>8</em><em>0</em><em>-</em><em>1</em><em>4</em><em>2</em><em> </em><em>=</em><em>3</em><em>8</em><em> </em>

➷ Figure out what you would need to do to get from 2.5kg to 1kg
You would need to divide by 2.5
Just divide the cost by this value:
2.5/2.5 = 1
1kg would cost £1.00
