B) The cost (x) for hiring and artist for a stage show for (y) hours is represente as 2y + x = 20.
Draw the graph 2y + x = 20 on the grid below.

The easiest way is to transform this equation to intercept form of straight line.

Intercept form of straight line:

where is the x intercept - where the graph intersects the x axis, and is the y intercept - where the graph intersects the y axis.

Given that,

On comparing with we get,

Hence, the graph shall cut the x axis and y axis at 20 and 10 respectively. This information is enough to plot the graph.

Graph: Refer to the attachment.
