Answer:
30
Step-by-step explanation:
This problem can be done without the Distance Formula (which is a way to find the distance between any two points in the plane).
The attached image shows the points and segments joining them.
PQ = 5 because the points are on the same horizontal line, and you can count spaces between them (or subtract x-coordinates: 4 - (-1) = 5).
PR = 12 because the points are on the same vertical line; count spaces or subtract y-coordinates, 7 - (-5) = 12.
The triangle is a right triangle, so the Pythagorean Theorem can be used to find the length of the hypotenuse.
The perimeter of the triangle is 5 + 12 + 13 = 30
Answer:
Option A: is the correct answer.
Step-by-step explanation:
The point-slope form of an equation of a line is given by:
Here:
m is the slope of the line
are the coordinates of the point from which the line passes.
Now looking at the given question:
Putting the values in the general form of point-slope form of equation of line
Hence, the point-slope form of given line is:
Observing the option given, it can be concluded that Option A: is the correct answer.
