Question

Plot the following points on a graph sheet. Verify if they lie on a line.
(i) A(2,1); B(2, 2); C(2,7); D(2, 4,5)
(ii) W(2,3); X(5,3); Y(5,5); Z(2,5)​

Answer 1

Answer:

(i) Lies on a line.

(ii) Does not lie on a line.

Step-by-step explanation:

(i) I assume D is in a 3D plane which would put it 5 units higher from the rest. If this is true then no, (i) would not be on a line. But since all of the x components are 2, this would be considered as a line.

(ii) All of the x components are different, thus putting them within different regions of the quadrant. When graphed, it makes a triangle.

Below I attached the points into a Desmos Graphing Calculator. The RED markings resemble (i). The BLUE markings resemble (ii).
