Distance from a point to a line (Coordinate Geometry)
Method 1: When the line is vertical or horizontal
, the distance from a point to a vertical or horizontal line can be found by the simple difference of coordinates
. Finding the distance from a point to a line is easy if the line is vertical or horizontal. We simply find the difference between the appropriate coordinates of the point and the line. In fact, for vertical lines, this is the only way to do it, since the other methods require the slope of the line, which is undefined for evrtical lines.
Method 2: (If you're looking for an equation) Distance = | Px - Lx |

Answer:
y = 4000 - 70x
Linear function.
Step-by-step explanation:
Let x = number of weeks.
In 1 week, he withdraws $70.
That means -70 in 1 week.
After the second week, he will have withdrawn 2 times $70, or
-70 × 2
After 3 week, he will have withdrawn -70 × 3
After x weeks, he will have withdrawn $70 × x,or simply -70x.
He starts with 4000, so after x weeks, he has 4000 - 7x.
Let y = the amount of money at week x.
The equation is
y = 4000 - 70x
This is a linear function.
Answer:
v=58
Step-by-step explanation:
All we have to do here is plug in the numbers for the corresponding letters. That means we are left with v=13+9*5. So then all we have to do is put it in the calculator and we get 58.
Answer:
it should be x=4
Step-by-step explanation:
The line that is perpendicular to
y
=
−
3
is a horizontal line, because horizontal and vertical lines (
x
- and
y
- axes for example) are perpendicular. Therefore, this line will take the form
x
=
n
where
n
is the
x
-coordinate of the point passed through. The
x
-coordinate of the given ordered pair
(
4
,
−
6
)
is
4
, so the equation must be
x
=
4
