Answer:
The three points to be plotted can possibly be;
(0, 4.5), (18, 0) , (22, -1)
Step-by-step explanation:
Given an equation of a straight line, we simply need to determine two or three points that lie on the line and connect them with a straight line. For the line given;
-4y = x - 18
y is always a function of x hence x is the explanatory variable. We simply obtain the values of y by first fixing values of x as follows;
we let x be any 3 values and determine the corresponding values of y.
Let x be 0, y is determined as;
-4y = 0 -18
-4y = -18
y = 18/4 = 4.5
Let x be 18, y is determined as;
-4y = 18 -18
-4y = 0
y = 0
Let x be 22, y is determined as;
-4y = 22 -18
-4y = 4
y = 4/-4 = -1
The three points to be plotted can possibly be;
(0, 4.5), (18, 0) , (22, -1)
