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.
