Question

quadrant graphing help? will medal

Answer 1

Given, which of the following describes the boundary line and shading for the second inequality in the system?

solid line, shade below
dashed line, shade below
dashed line, shade above
solid line, shade above

Answer 2

if there is a "solid" line under the < or >, you graph the line with a solid line
i.e. \( \le\) means use a solid line. just < means use a dashed line.

Answer 3

well when i graphed it it had both a solid, and a dashed ad it was shaded to the left lol thats why i got confused

Answer 4

when you write
y>x this says y is bigger than x
notice the "big end" of the > is next to the bigger side, and the small end of > is next to the smaller side

Answer 5

they are asking about the *second* inequality
they are asking just about
\[ y \ge x-4 \]

Answer 6

so you should be able to eliminate some of the choices, right?

Answer 7

do you use solid or dashed for
\[ y \ge x-4\]?

Answer 8

solid

Answer 9

yes. that means either first or last choice

next, does
\[ y \ge x-4\]
mean y is bigger than the right side or less than the right side ?

remember
when you write y>x this says y is bigger than x notice the "big end" of the > is next to the bigger side, and the small end of > is next to the smaller side

Answer 10

bigger right?

Answer 11

is y is bigger.
next, as y gets bigger do you go up or down ?

Answer 12

sorry im working on other work ^-^

Answer 13

um up i think

Answer 14

yes, to go up, you make y bigger.
anyway, the "good y's" are the y's that are bigger than the line y=x-4
or in other words, the y's above the line.
we shade in the "good y's"

Answer 15

so its the last choice?

Answer 16

yes

Answer 17

aw sweet i get it now
