So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
Answer:
A quick comparison of the sample variances suggests that the population variances <u><em>are same or almost equal.</em></u>
Step-by-step explanation:
The populations from which two samples are drawn are normally distributed.
The variable used to predict another variable is called an independent variable.
F- distribution is used for the test of two sample hypotheses of variances.
If two populations have equal variances then the test Statistic is nearly equal to 1.
<em>t= s²₁/s²₂i</em>
<em />
As the variances are almost or nearly equal the test statistic would be almost equal to 1.

I hoped i help! :) have a fabulous day!
You are looking for something "if A, then B" equals "if B, then A".
The only one that satisfy the above is B.
