Answer:

y= 5x - 3

Step-by-step explanation:

For the slope, use this formula (y2 - y1) / (x2 - x1)

I used (1,2) and (2,7) from the chart

plug 7 for y2, and 2 for x2

then plug 2 for y1, and 1 for x1

7-2 / 2-1 = 5/1 = 5 <-- this is the slope.

Find the y intercept by plugging in (1,2) into y=5x + b

2 = 5(1) +b

2= 5 + b (subtract 5 on both sides)

-3 = b

So the answer is y= 5x - 3

What does m equal 2+2m=6

Lorico [155]

2 + 2m = 6 equals m = 2.

First, subtract 2 from both sides. Your problem should look like: 2m = 6 - 2.
Second, simplify 6 - 2 to get 4. Your problem should look like: 2m = 4.
Third, divide both sides by 2. Your problem should look like: m = $\frac{4}{2}$
Fourth, simplify $\frac{4}{2}$ to 2. Your problem should look like: m = 2, which is the answer.

Makes 25 dollars an hour and gets a 10% raise

Svet_ta [14]

To find the current salary, we take 10% of $25 (the raise), then add it back into the current salary.

Current salary = (25×10%) + 25

= (25 × .10) + 25
= 2.50 + 25
= $27.50

So his raise was 2.50 and he now makes $27.50
