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:
A
Step-by-step explanation:
all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :
pay attention that here we have x=6 y=4
4<
we simplify we get :
4<4.5-3
4<1.5 which is incorrect so (6,4) is not a solution. moreover
notice that 4 is > than 1.5 so the point lies above the line
thus the answer is : A
you can also solve this problem by graphing the line and plotting the point (6,4) and hence you will notice that the point is above the line
