Create a spreadsheet (or an app in an environment where you can plot lines e.g. HTML 5 canvas) to plot the graph of a line.

• Q7) MFC: Algebra 2 (Long text)

Use the spreadsheet/app you created for the last question to plot the following lines:

1) y=3x - 5

2) y= -2x +4

3) y= -0.5x + 8

4) y= 3x - 2

5) y=-x-1

• Q10) The table below which represents some management... (Long text)

The table below which represents some management figures from a programming project:

 Month Budget Costs % Tasks complete 1 £10,000 £786 11% 2 £9,214 £786 16% 3 £8,428 £786 22% 4 £7,642 £786 32% 5 £6,856 £786 37% 6 £6,070 £786 38% 7 £5,284 £786 45% 8 £4,498 £786 49% 9 £3,712 £786 54% 10 £2,926 £786 58% 11 £2,140 £786 68% 12 £1,354 £786 69%

1) Work out the formula of the line on a graph where:

a) The X axis represent the month and the y axis represents the amount of money in the project budget

b) The X axis represent the month and the y axis represents the monthly costs

2) if I were to plot the month on the x axis and the % tasks complete on the Y axis this would be a straight line because the difference between the each month's figures is not the same.

a) What could I do with these figures to make a straight line which would best fit all the values (i.e. I need the same change each month)

b) Calculate a 'line of best fit' which represents X (time) against Y % completed.

• Q11) MFC: Algebra 2 (Visit page)

We have been looking today at the equations which represent a straight line.

You may be asked about equations of a curved line, which represent change.
