Answer:
![y=7x -7](https://tex.z-dn.net/?f=y%3D7x%20-7)
Step-by-step explanation:
We are given two points, the y - intercept and the x - intercept.
The y - intercept being: ( 0, -7 )
The x - intercept being: ( 1, 0 )
The equation of a line in slope - intercept form is:
y = mx + b, where m is the slope and b is the y - intercept.
We already have the y - intercept. So far we have:
y = mx - 7
What we're missing is the slope.
To find the slope, we can use this formula:
, where
and
are the x - coordinates of both points and
and
are the y - coordinates of both points.
![m=\frac{0-(-7)}{1-0} \\\\m=\frac{7}{1}\\m=7](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B0-%28-7%29%7D%7B1-0%7D%20%5C%5C%5C%5Cm%3D%5Cfrac%7B7%7D%7B1%7D%5C%5Cm%3D7)
We now have the missing piece, the slope, so the equation now is:
![y=7x -7](https://tex.z-dn.net/?f=y%3D7x%20-7)
It would be 6=-5 tell me if you got it right :)
The answer is, localities in Georgia can add a certain percentage to sales tax for their own needs.
Answer:
n = 10
Step-by-step explanation:
1<em>n </em>+ 1 = 11
Subtract 1 from both sides of the equation:
1n + 1 - 1 = 11 - 1
1n + 0 = 10
n = 10
The temperature went down by 10 degrees F. An exothermic reaction happened because the temperature went down so heat was released.
