Graph the lines by finding the points of intersection with the axes (intercepts):
Ostrovityanka [42]

To solve this problem you must apply the proccedure shown below:

1. You have the following function:

y=-\frac{1}{2} (x-1)

2. You can rewrite it as following:

y=\frac{(-x+1)}{2}

3. The line intersects the y-axis when x=0, therefore:

y=\frac{(0+1)}{2}=\frac{1}{2} =0.5

4.  The line intersects the x-axis when y=0:

0=\frac{(-x+1)}{2}\\ 0=-x+1\\ x=1

5. Now plot the points (0, 0.5) and (1,0) in a graph , as you can see in the figure attached.

Therefore, the answer is: The points of intersection are (0, 0.5) and (1,0).
