 * x>5 on a number line is a straight line with an open circle and shade to the right. x>5 on a coordinate plane is also a striaght line that is dotted and u shade above.
 * x<=3 on a number line would be a straight line with a closed circle and shade to the left. x<=3 on a coordinate plane would be a solid straight line and u shade below.
 * y<2x+1 you would plot 1 on the y-int and then go up 2 and over one to make ur line and u would shande below.
 * To know which way to shade you would look at the sign if its a less than or less than or equal to sign you shande below because the y value is less. If its greater than or greater than or equal to then you shade above.

Solution to both= (-5,6) solution to 1= (2,8) you can check if your solut6ion is right by plugging in your points into the inequalities.

y=.30x+40

A.) If i needed to change something to look for a cheaper price i would lower the y-int and the slop so it would be significantly cheaper. B.) If i wanted to charge cheaper for my compant i would lower my y-int( the started payment) to 30$ because people will see that its ONLY .30 $ for each mile thats a low amount of money and if i have a lower starting paying more people will think thats its a way better price.

y=.30x+30
