To figure this out simply, find where the first number is on the x axis and then move over to the y axis, the Horizontal line is the x and the vertical is the y.
The systolic pressure is 130 mmHg
Sorry for bad drawing but I think that shows it
By using the concept of line, coplanar, non parallel lines always intersect
Definition of perpendicular and skew lines has been given
What is a line?
A geometrical object which has only length but no breadth and height is called a line
The lines which are coplanar and are not parallel will intersect at some point
Two lines are said to be perpendicular to each other if the angle between them is 90°
The lines which are not parallel, non coplanar at do not intersect are called skew lines.

Answer:
1: x = 19 y = 16 ; 2. x = 5 y = -4
Step-by-step explanation:
To check your work plug the numbers back into one of the equations and see if it's true.
For example:
10(19)-9(16)=46
46=46
1. I distributed 3 to all the numbers so that 9y and -9y would cancel then you add like terms.
2. I distributed -4 to all the numbers so that 4x and -4x would cancel. Then add all like terms.
Once you get x or y plug it back into one problem to get the other variable.
Hope this helps!
