is the correct answer and this expression can be simplified to find the slope of the line of best-fit in the scatterplot below by using the the slope equation : 
.
What is Slope of the Line?
The slope of the line is the measure of its steepness and direction. Without using a compass, determining the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or none at all.
Any two distinct points on a line can be used to calculate the slope of that line. The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points on a line. In this article, we will learn about the slope-finding method and its applications.

#SPJ1
Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
Squaring both sides; we have:
n = 67.65
Therefore, the required sample size = 67.65
Is that the full question
Pick b I think hahahahaha
Scholastic Aptitude Test
While the first College Board test was administered in 1901, the organization didn't introduce the SAT until 1926. At the time, the acronym SAT stood for Scholastic Aptitude Test
