Question 164314: this question is from a worksheet
Graph the inequality x+5y>5 using the slope and intercept method. i have solved this problem and got 0>5 and slope of -1/5 and y intercept of 1, my only problem is to decide whether to shade above or below. i have read the explanations given on the algebra.com, but im still having trouble understanding it. can you please explain it to me in a more simpler way considering this example along with it. thanks fatma

x%2B5y%3E5
5y%3E-x%2B5
y%3E-x%2F5%2B1
+graph%28+300%2C+300%2C+-5%2C+5%2C+-5%2C+5%2C+-x%2F5%2B1%29+

So far, so good.
OK, picking the point.
I always choose (0,0), if possible.

Go back to your inequality.
If (0,0) is in the solution region, the inequality will be true.
If (0,0) is not in the solution region, the inequality will be false.

y%3E-x%2F5%2B1
0%3E-0%2F5%2B1
0%3E1
False, so (0,0) is not in the region.

Since (0,0) is below the line, the region above the line is the correct region.
