Need help in Maths Qs.

Take Your Pants Off

I cant seem to get Q4 at all especially part a
Part of Q9 I cannot get part f and g

Take Your Pants Off

I am not sure if i got part d right in relation to Q 10.
Also I cannot get e, do you put x equals 0 and y equals 0.
Because I tried that with the equation I got from previous question but the x value sums up as fraction so maybe the equation is wrong for part d

Dude, it's July

I haven't done co-ordinate geometry for over a month now, I'll have a look at them this evening.

But seriously, go get wasted or something :pac:

Q4, a lot of people get caught out with this question. Once you know about the properties of the equation of the line, it's easy.

When an equation of a line is written in the form y = mx + c, m = slope and c = y intercept.

You can start by re-writing the four equations in the form y = mx + c. You'll see that 2 of them have equal and positive slopes and the other 2 have equal and negative slopes. Looking at the y intercepts of the lines (c value), 2 of them have a y intercept of 4 and the other 2 have -2.

Now you know which ones are which. Positive slope + y intercept of 4 = m, negative slope + y intercept of 4 = j and so on. Once you understand how it works, you'll probably be able to recognise and label them just by looking at it.

For part b, mark your y intercepts and then just go from there.

Once you do b, part c should become more clear.



The other two are full Section B questions, I'll do them tomorrow
