Answer:
5x -y = -37
Step-by-step explanation:
One way to find the coefficients A and B is to use the differences of the x- and y-coordinates:
A = Δy = y2 -y1 = 2 -(-3) = 5
B = -Δx = -(x2 -x1) = -(-7 -(-8)) = -1
Then the constant C can be found using either point.
5x -y = 5(-7) -2 = -37
The equation of the line is ...
5x -y = -37
_____
<em>Additional comment</em>
This approach comes from the fact that the slope of a line is the same everywhere.
The "standard form" requires that A be positive, so we chose point 1 and point 2 to make sure that was the case.
Its a ray. The definition of a ray is "A line which starts at a point with given coordinates, and goes off in a particular direction to infinity" A is the point and the arrow shows that it goes until infinity.
Answer:
"vertical" (y axis), "lateral" (x axis), and "horizontal" (z axis)
Step-by-step explanation:
It should be 50(x+5). Let me know if you want more of an explanation.
Here's how you can do that.
Explanation:
The problem tells you that the product of two consecutive odd integers is equal to
783
.
Right from the start, you know that you can get from the smaller number to the bigger number by adding
2
.
You need to add
2
because if you start with an odd number and add
1
, you end up with an even number, which is not supposed to happen here.
odd number
+
1
=
the consecutive even number
×

2
=

√
So, if you take
x
to be the first number, you can say that
x
+
2
is the second number, which means that you have
x
⋅
(
x
+
2
)
=
783
