OK, so what you need to do is pick to points on the line
This is the attanchment with the choices
and you know the information i am on number 1.
We have two that are shown already
Is it 2.4 and -4.1
Yep, thats the two points
So how do i write this is is choice C
So we need an equation of the form y = mx + c where m is the slope and c is the y-intercept.
I need to plug them in
So now we need to find all the components, that is, m & c
C is easy, C (the y-intercept) is the point where the line crosses the y axis.
Do i idividually do it or i try crmming both of them in one equation
is it y=1/2x + 3
One at a time, so first we find C. Can you see on the picture where the line crosses through the y axis?
Yep, you are correct, it is y = 1/2x + 3
So its C what i mean by C is the third answer!
By the way can yiou help me on four more but help me correct them!
I am on Number 2
are you there
yes i need help correcting
The second attanchment is the one problem i need help on!
Can anyone help me?
I think it is y = -2
Umm so its y=-2?
do you have graphic calculaor?
Can you tell me if i got it correct?
yes -2 is correct
y=-2 is correct. because you have a straight horizontal line (y), thus no x...If it is vertical then you have x not y
Sorry i was just having dinner before, but well done =)
