7 0

Answer:

D) When x=2, y=14
When x=4, y=28

Step-by-step explanation:

By using slope= y2-y1/x2-x1

I get (1,7) and (3,21) from the table

slope= 21-7/3-1= 14/2= 7

Then I plug in the values into y=mx+b

7= 7(1) +b

b= 0

Getting an equation of y=7x

When x= 2

y= 7(2)= 14

When x= 4

y= 7(4)= 28

Answer:

495 cm

Step-by-step explanation:

When you do the subtraction, whatever is left (the decimal part) is the length in cm when multiplied by 100.

Solution

Remaining rope = starting length - what was used.

Remaining rope = 6.15 - 1.2

Remaining rope = 4.95 meters

Answer

The remaining rope = 4.95 * 100 = 495 cm
