Do you remember the equation of the line? y = mx+b?

|dw:1438422409021:dw| for reference

4. arindameducationusc

put values x=-8 and y=-4, you will get your answer easily which satisfies

5. Astrophysics

Essentially inequalities are like equation of a line with a few extra rules, such as if it's <, >, then we will have a dashed line, and if we have $\le ~~~\text{and}~~~\ge$ you will have a solid line. Just with that information we can eliminate two of the options, so which ones can we eliminate?

6. arindameducationusc

example==> Option A, 4(-8)-3(-4) is not greater than -12, so cut that out

7. Astrophysics

What @arindameducationusc is showing you is the intercepts, that's a good way to graph quickly and figure out which one it is.

8. arindameducationusc

You there @dom4958 ?

9. arindameducationusc

Ya, thats a quick way but equation y=mx+c also should be remembered for straight lines! Thumbs up @Astrophysics

10. anonymous

@arindameducationusc so it would be b?

12. anonymous

omg its d. thanks @Astrophysics

13. Astrophysics

Yes, but make sure you understand how to do it using equation of line/ intercepts, what ever because the sign may not always be reliable but for this problem it was obvious without doing any work :P
