can someone please explain how to get the answer for 1b please ty!!
#equation of line

sketch it
it's just asking you to write the line of anything that passes through (0,1)
so essentially y=mx+1
you can choose the gradient
y=-2x+1 passes through, y=1 passes through, y=79x+1 passes through

Assume that the line is perpendicular to line AB
Easier to get the gradient then
thorny lynx
Assume that the line is perpendicular to line AB
Easier to get the gradient then
/jc, why does perpendicular lines matter here
outer snow
It doesn't
I'm just saying that it helps to find the gradient
gradient of the the line is -1/gradient ab

I would've imagined m is irrelevant here, as the example given is 5. you could realistically get away with writing $y=mx+1, m \in \mathbb{R}$

and they would be inclined to mark you as correct, since you've specified that for any m, there exists a straight line going through coords (0,1)
outer snow
Isn't that the answer?
thorny lynx
Isn't that the answer?
what do you mean?
thorny lynx
well not the only correct one, but I would imagine it's an example of a correct solution, yes
outer snow
I did it in my way and the gradient is -2 ig it's wrong
thorny lynx
having a gradient of -2 is fine, you would just have to have y=-2x+1
this still passes through (0,1)

No not the only answer, it can be any answer such that it follows the condition listed:

okay ty both for your help
