y%3C=+-x%2B18
Solved by pluggable solver: PLOT any graph
Graphing function y%3C=-x%2B18:

graph%28+500%2C+500%2C+-20%2C+20%2C+-20%2C+20%2C+y%3C=-x%2B18+%29



x+%3E=+4
here is the graph x=4, for all y x=4
Solved by pluggable solver: Graphing Linear Equations

-1%2Ax+=+-4


x+=+-4%2F%28-1%29


x+=+4


This is the vertical line that cuts through 4 on the x-axis and the graph is shown below





The slope of this line is undefined. All vertical lines have an undefined slope since rise/run = x/0 and division by zero is undefined.




y+%3E=+3
Solved by pluggable solver: Find the equation of the line(with graph)---slope a nd y-intercept:given

Using the slope-intercept form,
y=mx%2Bb
where m=slope, b=y-intercept,
and, substituting the values m=0 and b=3,
y=%280%29x%2B3
And the general equation is,
%280%29x-y%2B3=0
