1) y=-3x +c the gradient is negative so that tells you which direction the line goes and since c is positive the y intercept is above the x axis. Then draw the graph of 1/x if you don’t know it you need to learn it and then shift it all up 5 units. An asymptote is a line the curve approaches but never meets. For example the graph of y=1/x has asymptotes of y=0 (x axis) and x=0 (y axis)

Set the equations equal to each other, rearrange in the form ax^2 bx c=0, then use the discriminant. We know it’s 2 distinct points therefore the discriminant will be greater than 0. Then simply rearrange again. Then you can manipulate this to work out the range of possible values of c
