How are slopes and y intercepts to the number of solutions of a system of the liner

Leona [35]

We assume a linear system with 2 variables.

If the slopes are the same, and y-intercepts are different, there are 0 solutions.

If the slopes are different, there is 1 solution.

If the slopes are the same, and the y-intercepts are the same, there are ∞ solutions.

From the data collected, the proportion of voters that view her favorably is

used at a given confidence level to determine the true proportion of voters

that view her favorably.

Therefore;

The statistical method that would be best for her to use is the

finding of the confidence interval which is a inferential statistic method.
