Question

25 Points.

Answer 1

That is the graph, you figure out the y value of an (x,0) coordinate by dividing whatever the x value is by 2, so you can find out all the points in this line by using this expression: (x,x/2)

Answer 2

y=1/2x

Solution:
Y=mx + c
M represents the gradient/slope and C is the y intercept
M= 1/2 and C= 0
