The given equation is y=4x−52
Here x is the independent variable.
We assign any 4 values of x and obtain the corresponding values of y.
x=−2
⇒y=−10.5,
x=−1
⇒y=−6.5,
x=2
⇒y=5.5.
x=4
⇒y=13.5
So, the ordered paires of values of (x,y)=(−2,−10.5),(−1,−6.5),(2,5.5) and $ (2,13.5).
Now we plot them on a graph.
The line passes through (0,−2.5) and m=4..
