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
