hey theree :D

wolfe8 · Answer

Ah so here you will have to figure out the equation of the straight line first :)

anonymous · Answer

i'm not sure how i'm supposed to do that :$

wolfe8 · Answer

Ah okay. So recall the general form, y=mx+b where m is the gradient and b is the y-intercept. For this question, finding m and b should be enough to figure out the equation :)

anonymous · Answer

ooooo wait the correct inequality isn't listed. am i right? isnt the sign supposed to go the other way

wolfe8 · Answer

I see the answer listed :) Can you tell me what you got for the line equation?

anonymous · Answer

pellet :/ ummmmmmmmm i really don't know lol what is it?

wolfe8 · Answer

Well you can see the intercept is at y=3, and the gradient is 6. Now, I will assume you know how to find the gradient. So the equation is y=6x+3. Write this as an inequality and get $$y <6x+3$$ because it is to the left of the line. Rearrange that you will get?

anonymous · Answer

6x-y<-3 ?

wolfe8 · Answer

Can you tell me why it is a -y on the left side?

anonymous · Answer

because to get the 6 on the other side don't you have to subtract 6 on both ends idk

wolfe8 · Answer

But to get 6x to the other side you have to subtract both sides with 6x. Leaving -6x on the left and no change to the y :)

anonymous · Answer

ohhh trueeeeeeeee. so it's really -6x+y<-3 ?

wolfe8 · Answer

Yup yup. :)
