Given:
The equation of a straight line is
[tex]y=20-x[/tex]
The x value of a point on the line is 14.
To find:
The y value of this point.
Solution:
If a point (x,y) lines on line, then the equation of line must be stratified by that point.
We have, the equation of a straight line.
[tex]y=20-x[/tex]
Putting x=14, we get
[tex]y=20-14[/tex]
[tex]y=6[/tex]
Therefore, the y-value is 6 when the x-value is 14.
