Answer:

Step-byThe equation of the line with slope 2 is y=2x+b, b is a constant which should be determined. The line passes via through points (1, 2) and (3,y)

(1, 2): 2=2+b --> b=0

So, the equation of the line is y=2x. Now, when x=3, y=6. So the line y=2x passes through points (1, 2) and (3, 6). (3,y)=(3, 6).-step explanation:

Answer:

15x $\geq$ 345

x = number of hours she works

Step-by-step explanation:

First: find the inequality symbol

If she wants to earn at least 345, she wants to make 345 or more

that means you use the greater than or equal symbol ( $\geq$ )

Next, if she makes 15 dollars an hour, x has to be the number of hours she works. The left side of the inequality would be $15* number of hours, or 15x

Thus, your inequality would be 15x $\geq$ 345
