Answer:</h2>
First we must find the opposite-reciprocal of the original slope.
current slope: 
new slope: 
Using the new slope and the given point, we will plug them into slope-intercept form and solve for b, the y-intercept.

The y-intercept is
.
Now, we can write the formula for the new line.
Slope-intercept form: 
Point-slope form: 
Answer:
n=-19
Step-by-step explanation:
-9+n/4=-7
Multiply 4 on both sides
-9+n=-28
Add 9 on both sides
n=-19
Is is the first one. 1600=.45x
The answer would be 14/15
Find a common denominator that both of the fractions can use. An easy way to do this is simply multiply the denominators together. So for 3/5 you would multiply by 3 to get the fraction 9/15 and then multiply 1/3 by 5 to get 5/15. Add both 9/15 and 5/15 to then get 14/15.
I think the answer is C-No solutions
