Answer:

Given, y be the total amount of paid and x be the number of days.

Then, linear equation in two variables is:

y=2[5 \times 1+1 \times (x-1)]y=2[5×1+1×(x−1)]

y=2[5 +(x-1)]y=2[5+(x−1)]

y=2[x+4]y=2[x+4]

y=2x+8y=2x+8

For plotting the graph, taking two points.

Put x=0x=0

y=2 \times 0+8y=2×0+8

y=8y=8

We get (0,8)(0,8) .

Next, put x=1x=1

y=2 \times 1+8y=2×1+8

y=10y=10

We get (1,10)(1,10)

Plotting these points on the graph and joining them, we get a straight line as shown.
