Refer the explanation section.

Explanation:

The given function is linear. The curve will be a straight line.
Find two points. Plot them on a graph sheet. Join them with the help of a straight Line.

Given -

$y = \frac{1}{2} x - 5$ $y=1/2x-5$

Find the Y - intercept

At $x = 0; y = \frac{1}{2} (0) - 5$ $x=0; y=1/2(0)-5$

$(0, - 5)$ $(0, -5)$ is one of the points.

For the other point we would normally find the X-intercept.

If we did that with this equation we would create a fraction. It may be little difficult to fix that point. So, instead, assign a value to $y$ $y$ so that you get a whole number as x-co-ordinate.

In our case we shall assign $+ 1$ $+1$ as y-co-ordinate.

At $y = 1; 1 = \frac{1}{2} x - 5$ $y= 1; 1=1/2x-5$

$\frac{1}{2} x - 5 = 1$ $1/2x-5=1$
$\frac{1}{2} x = 1 + 5 = 6$ $1/2x=1+5=6$
$x = 6 \times 2 = 12$ $x=6 xx 2=12$

$(12, 1)$ $(12, 1)$ is another point.

Plot the points $(0, - 5) and (12, 1)$ $(0,-5) and (12,1)$

Join them with a straight line. You get the curve.
