What is the Y-intercept in a linear equation?

Back

The Y-intercept is the value of y when x is 0, representing the starting point of the line on the y-axis.

How do you find the first four terms of an arithmetic sequence given a recursive formula?

Back

Start with the first term and repeatedly add the common difference to find subsequent terms.

What is the formula for finding the nth term of an arithmetic sequence?

Back

The nth term can be found using the formula a_n = a_1 + (n-1)d, where d is the common difference.

How can you determine if a correlation is strong or weak?

Back

A strong correlation will have points closely clustered around the line of best fit, while a weak correlation will have points more spread out.
