Question

can you graph the equation?

Answer 1

yes. when x=1, y=.5. so basically just divide x by 2, then find where it is on the y- coordinate, and graph where it meets

Answer 2

Plug in x = 0 and it leads to y = 0. This is because 

y = (1/2)*x
y = (1/2)*0 ... x has been replaced with 0
y = 0

So the point (0,0) is on the graph of the equation.

Now plug in x = 2 and follow the same steps as above
y = (1/2)*x
y = (1/2)*2 ... replace x with 2
y = 1 
So x = 2 leads to y = 1 giving us the point (2,1)

Plot the points (0,0) and (2,1). Then draw a straight line through these two points to draw the graph of the equation.

See attached for a visual. 

Side Note: 1/2 = 0.5 so y = (1/2)x is the same as y = 0.5x
