Answer:

y = 2x - 8    OR     4 - 2x = -4 - y

Step-by-step explanation:

Use the point-slope form m(x₁-x₂) = (y₁-y₂); m means slope

plug in your numbers:

2(2-x₂) = (-4-y₂)

4 - 2x = -4 - y

or to put it into Y=mx + b:

y = 2x + 8

Trevor is swimming laps to raise money for the local food bank. He earns $1.85 per lap and has already swum 23 laps.
Studentka2010 [4]

Answer: L greater than 31

Step-by-step explanation:

Trevor is swimming laps to raise at over 100 dollars for the local food bank. He earns $1.85 per lap and has already swum 23 laps.

This means that the total amount that he has raised is number of laps that he has swum × the amount he earns per lap. Therefore,

Amount that he has already raised

= 1.85 × 23 = $42.55

100 - 42.55 = 57.45

He still needs to raise an amount greater than $57.45

To raise this amount, he needs to swim more laps. Number of laps that he needs to swim will be

57.45/1.85 = 31.05

Approximately 31 laps

Let the number of laps that he needs to swim be L

The inequality to show how many more laps Trevor needs to swim in order to raise more than $100 will be

L greater than 31
