Question

Determine the type of boundary line and shading for the graph of the inequality -2x - y < -6

Dashed line with shading on the side that includes the origin.

Solid line with shading on the side that does not include the origin.

Dashed line with shading on the side that does not include the origin.

Solid line with shading on the side that includes the origin.

Answer 1

For <= and >= line will be solid because it's included
For < and > line will be dashed because it's excluded
You can rewrite equation as y>-2x+6

Answer 2

oooaky i get it in the y acxes it will be shaded and in the x axes it will solid

Answer 3

there for the answer will be the the third choice

Answer 4

correct, good work

Answer 5

thanks

Answer 6

help i went to know if i got this one right please

Answer 8

A

Answer 9

i belive it is the first one right

Answer 10

yes correct, the first one or A :)

Answer 11

thaks :}

Answer 12

y<2x+4

You can plug origin (0,0) into equation of a line.
If it's true statement - shade the side with origin.
Otherwise shade opposite side.
