C becuase it makes the most sense
You need to come up with an array of answers for x and y that will be greater than 0.
x+4y>0. example if x is -1 and y is 1 will this be correct.
-1+(4*1)>0, -1+4>0. 3>0? Yes
if x is 1 and y is -1 then the equation becomes 1+(-4)>0 -3 is not>0 so it's not in the array
x could be -3 and y 1
You will plot a line to show all the answers.

Answer:
d. Reject H0 if t < -1.6604
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the mean number of tissues used during a cold is significantly less than 60.
Then, the null and alternative hypothesis are:
The significance level is 0.05.
The critical value for a level of significance is α=0.05, a left-tailed test and 99 degrees of freedom is tc=-1.6604.
The decision rule is that if the test statistic is below tc=-1.6604, the null hypothesis is rejected.
