ANSWER:
[a] A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).
[b] In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “Slope-intercepts form”.

Answer:
²⁵C₅ = 53130
Step-by-step explanation:
number of people in the club = 25
number of people to be selected in the group to attend conference = 5
number of ways of selecting this group from 25 people is same as selecting 5 objects from 25 distinct objects = ²⁵C₅ (Selection)
= 
= 
= 21×22×23×5
= 53130
∴ <u>Number of ways of selecting this group from 25 people = 53130</u>
