Question 353122
Hi,
.
The inequality {{{x <= 3}}}describes all values of x that are less than or equal to three
.
To graph{{{x <= 3}}}, one would use a number line, a closed circle on a shaded arrow pointing to the left. (closed circle on 3 shows the 3 is included in the graph of the inequality {{{x <= 3}}} )
{{{number_line( 600, -10, 10,3 )}}}
.
2x + y > 7  
y>-2x + 7  
*Note: if the > were an = sign, this would represent the equation of a line y = -2x + 7 with points  (0,7) and ( 7/2, 0) on the line.
.
As y is greater than -2x + 7, one would shaded the area above the line (the line itself is not included as being part of the graph of this 'inequality')
.

{{{graph( 300, 300, -10, 10, -10, 10, -2x + 7)}}}
