Question

Which inequality will have a dashed boundary line with a shaded area above its graph?

7x − y ≤ 3

x − y ≤ 4

2x − 9y > 2

4x + 7y > 3

Answer 2

dashed boundary line means there is no equal sign in the problem...that eliminated the first two
shaded above means it is greater then.

Now turn your inequalities into y = mx + b form
2x - 9y > 2 --- subtract 2x from both sides
-9y > -2x + 2 -- divide by -9...and change inequality sign
y < 2/9x - 2/9
this says y is less then.....we need greater then...this is not it

try the next one..
4x + 7y > 3 --- subtract 4x from both sides
7y > 4x + 3 -- divide by 7
y > 4/7x + 3/7
this says y is greater then...this is the one we want

any questions ?

Answer 3

i have one another question

Answer 4

Which inequality will have a solid boundary line and a shaded region above its graph?


x − y ≥ 3



2x − 3y ≤ 3



3y − x < 2



2x + y < 7
