Answer 3

x=y+5

subtract 5 from both sides to rearrange to:
y=x-5

m = 1 (gradient)
c = -5 (where the graph line intersects the y axis)

(0,-5) is a point on the line

to plot the graph more accurately u ideally need another 2 points.
use the equation: y=x-5 to get another 2 points

y=5-5
y=0 (when x = 5)
(0,5) is a point on the line

y=3-5
y= -2 (when x = 3)
(3,-2) is a point on the line

you have three points (0,-5), (5,0) and (3,-2). Draw an extended line through the middle of all three points and you have graphed x=y+5
