What am I doing wrong on this question.

What am I doing wrong on this question.

just draw the line and find the solutions like you did with the other graph (first part of the question)

hint - the easy way to draw is to draw and translate the graph "down" the y-axis by 19 units

you needed the graph of y=5-2x

That is not the method required by the question

tbh it's not that clear what method the question is asking for. And god knows what that stuff at the bottom is supposed to mean. y=-6 [2] x=-1 etc
another way would be to draw and see where they intersect

(work out what gives you)

It says --- by drawing a suitable line

They are zed's incorrect answers [and the marks available]

The web site this question comes from is littered with errors.

yeah. It's a pretty poor question, tbh. Rather ambiguous

It's not ambiguous . The suggested solutions are simply rubbish.

and what is that random blue line doing on the graph?

That will also be Zed's answer

this is what the page looks like

though i agree that the site is far from perfect
..Just write the coordinates of the point where the line crosses the X and Y axis?
(Original post by TenOfThem)
That will also be Zed's answer
but he appears to have entered y= -6 as his answer. That blue line is not y= -6
(Original post by Plato's Trousers)

No

But we had already established that he did not know what he was doing

This is not correct

No

I thought you were saying he had to enter the line required in the y= box. Then the program would draw it on the graph? He hasn't entered the equation of that line so how did it appear on the graph?
