Answer: 
Step-by-step explanation:
The Slope-intercept form of the equation of the line is:
m: is the slope.
b: the intersection of the line with the y-axis.
The equation of the line 
has:
If both lines are parallel, then their slopes are equal. So the slope of the other line is:
To find "b", substitute the given point and the slope into ![]y=mx+b](https://tex.z-dn.net/?f=%5Dy%3Dmx%2Bb)
and solve for "b":
Then the equation of this line is:
the temperature differential is based on the numbers on a line with the negative numbers left of zero and the positive numbers right of zero.
Using -12 on the number line, add 25 to it to get the noon temperature tomorrow.
Awnser -12 + 25 = 13
The temperature tomorrow at noon will be 13 degrees.

Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
