I need to due it by Friday. Thanks So in the first pic, only the value of a is correct.
Notice
is on the x axis, so what must c be?
For the coordinate of b, look across to a point along the line.
For the Q in the second pic, note that the product of the slopes of perpendicular lines is -1.

I need to due it by Friday. Thanks Do you need help with questions 4 and 6 on the 3rd image? Not sure if you need help on those or if they just ended up being in the pic when you tried to take a pic of the middle q.

I find the last 2 pics really difficult but I would be really glad if you could help me with the rest of the questions.

Yeah I need help on those questions as well. Is it easy?

For q 4 rearrange the equation to make y the subject, then you should be able to manage from there.

I have no clue.
SorryOriginal post by strangepath
I have no clue. Sorry
SorrySee what it is directly below?
And what it's y coordinate must be as it is on the axis?

And what it's y coordinate must be as it is on the axis?
It is below Point B?
and the y coordinate must be 0?
So N is (2,0)?

Precisely
Now, how long is the line BN?Original post by joostan

Now, how long is the line BN?Is the answer 4?
Original post by strangepath
Is the answer 4?
Yes it is. Now what about AC?
Original post by joostan
Yes it is. Now what about AC?
AC = 8?
Area of ABC = 16?
BC = 5?
are the above correct?
I don't know how to do the length of AM.

Yes they are all correct
You know the area of the triangle. were you to rotate the page to make BC the base, would this affect the area of the triangle?

WOW
that's a very interesting question. Let me guess mhmm yes?Original post by strangepath

that's a very interesting question. Let me guess mhmm yes?No. . .
Original post by joostan
No. . .
Oh
how do i solve the length of AM though?
Original post by joostan
No. . .
I am such an idiot, the answer was written right there
