Answer with explanation:
⇒ y=8.1 x
This is a Linear equation depicting linear relationship between y and x which is between the number of hours Alexander works, x, and the dollar amount he earns, y.
To determine a line you need two points.
→Put, x=0,in y=8.1 x, gives y=0 gives a Point (0,0).
→Put,x=1 gives , y=8.1 × 1→y=8.1 gives another point (1,8.1).
→So, Drawn a line passing through (0,0) and (1, 8.1),which is the required image of the equation given.
