Do you know the answer to this?

The new 12 PM temperature should be 2.5 degrees Fahrenheit. And Dana is correct; you can subtract 1.4 from 2.5 (2.5 - ( -1.4) to find out the change in temperature from 6 AM to 12 PM on the second day.

Note:

Because of the direction the subtraction problem is set up between 2.5 and -1.4, the two negative signs will result in an addition sign according to the rules of algebra. Meaning that, the difference between -1.4 and 2.5 is approximately 3.9.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
