How do you solve these 2 systems of inequalities using graphing?

lxl<(or equal too) 3 lyl>1

and the two l’s are absolute valuse bars fyi.

and

y>x-3

lyl< (or equal too) 2 I understand how to graph and shade and stuff but how do you do the absolute value?

Absolute value is really quite simple once you get it. All it means is distance without a + or – direction.

You can write |x|<=3 as -3<= x <= 3 Or, |y| <=2 as -2 <= y <= 2 Think of taking two steps away from a spot on the floor. Abs value just means that you are two steps away and ignores the actual direction you've moved in.

you would shade the x-area between +3 and -3

where the y-area is above +1 and below -1

The area is that has X values when the absolute vale is less than or equal to 3.

in the second problem,

you should already know to shade the y-area above the line y=x-3, but only the x-area between +2 and -2

for a million and a couple of you ought to graph them, substitute them to y=3x-6 and y=2-x. Then the place the two lines bypass is the respond, in the event that they bypass at (3,4) that is one answer for substitution y=3, then positioned this into first one 3=5x-7 upload the two equations? uncertain? final one, draw, yet use dotted lines, then colour above or under the line (i exploit guess and attempt to ensure which factor)
