Answer/Step-by-step 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 = 1/2 x - 5
Find the Y - intercept
At x=0;y=1/2(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 so that you get a whole number as x-co-ordinate.
In our case we shall assign +1 as y-co-ordinate.
At y=1;1=1/2x−5
1/2x−5=1
1/2x=1+5=6
x=6×2=12
(12,1) is another point.
Plot the points
(0,−5) and (12,1)
Join them with a straight line. You get the curve.
