Question

The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y. Which is the graph of the equation y = 8.1x? Image for option 1 Image for option 2 Image for option 3

Answer 1

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.

Answer 2

Start the graph at the y-intercept.  At 0 hours, he will make $0, so (0, 0) is the y-intercept.  From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph.  The graph is attached.
