Question

x+y<0

graph inequality in a coordinate plane

Answer 1

First solve for y


x+y < 0


y < 0-x


y < -x


Now graph the line y = -x


Make this a dashed line


Then shade below the dashed line

Answer 2

how do you graph it ?

Answer 3

to graph the line y = -x, you need two points

to find any point, you plug in a value for x to get corresponding value for y

Answer 4

ex: if x = 2, then

y = -x

y = -2 ... plug in x = 2

so we have the point (2,-2)

Answer 5

oh i understand thanks !

Answer 6

that's great, yw

Answer 7

what type of lines are dotted and waht kinds are solid ?

Answer 8

if you have a line under the inequality sign, then it will be a solid boundary line

if not, then it will be a dashed boundary line
