4)a solid line, shaded above the line

Question

heisenberg · Answer

what do you think?

anonymous · Answer

i think that it's 2) a broken line, shaded above the line

heisenberg · Answer

a broken line would just be >
a solid line is used to indicate inclusiveness, like ≥

anonymous · Answer

so it;s probably 3 than. a solid line  shaded below the line

heisenberg · Answer

why below?

anonymous · Answer

because it's -2 right?

heisenberg · Answer

no that's just the y-intercept of the equation. you shade where the inequality suggests. in this case it's greater than, so everything ABOVE this equation (including this equation) is valid.

anonymous · Answer

ugh i feel silly! thankyou though!

anonymous · Answer

so for y ≤ 7 − 2x it would be a broken line, shaded above the line right?

heisenberg · Answer

no. it is less than, which means below.

a broken line is for < and >, and solid line is for ≥ and ≤

anonymous · Answer

ah! i really do get it now. thankyou :)
