We know how many miles he drove and the speed that he drove. We do not know how long i took him to drive that distance.
To find the time it took, divide the distance by his speed:
325 miles / 65mph = 5 hours.
21x-9+63=180
21x+54=180
21x=126
x=6
The point-slope form:

We have the points (2, 2) and (0, -4). Substitute:

The standard form:

<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>subtract y from both sides</em>

<h3>Answer: 3x - y = 4</h3>
Answer:

Step-by-step explanation:
To find the distance, we first do B - A, where B is (-6, 7) and A is (-1, 1):
(-6, 7) - (-1, 1) = (-6+1, 7-1) = (-5, 6)
Imagine it as a triangle, where the hypotenuse is the distance, and -5 and 6 are the lengths of the sides.
To find the hypotenuse (Pythagorean Theorem): 
The answer is the square root of 61.
