Answer:y=0
Step-by-step explanation:
slope=(y2 - y1) ➗ (x2 - x1)
1/2=(y-2) ➗ (3-7)
1/2=(y-2) ➗ -4
Cross multiplying we get
-4=2(y-2)
-4=2y-4
Collect like terms
-4+4=2y
0=2y
y=0

2. the square root of 197 or 14.0
Answer:
The distance is 
Step-by-step explanation:
we know that
The formula to calculate the distance between two points is equal to
we have
substitute the values
Answer:
Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work. The constant is 23.50.
Part B: He will have $503.50
Part C: The coefficient would change, because the amount per car changes, not the amount of cars.
Step-by-step explanation:
A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached.
We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.
This is the solution to your equation.
