Ya and Yb represent continuous linear relations. Some values from the relations are shown in the table below. Graphically solve the linear system.

The solution to the continuous linear relation is: (2,-7)

The data on the table can be presented as:

Relation A

Relation B

Plot the points of each relation and draw a line through the points (see attachment)

Write out the point of intersection of the two lines.

Hence, the solution to the continuous linear relation is: (2,-7)
