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:
74.4
Step-by-step explanation:
It is already rounded to the nearest tenth of a percent. If it was rounded to the nearest percent it'd be 74%.
<span>A line thru (5,1) with slope of 3
y - 1 = 3(x - 5)
y = 3x - 15 + 1
y = 3x - 14

Step-by-step explanation:
Answer:
<h2>The option B and D are the equations.</h2>
Step-by-step explanation:
Let, the total number of students are x.
The number of students having the ticket is 
.
It is given that the number is 20.
Hence, 
.
Option B is the equation.
Option D is also the same.
The difference is just, the variable is wriiten in the other side.
