The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.
an =a1+d(n-1)
where d is the common difference
d=5-8
d=-3
a1=8
an =8-3(n-1)
Choice C
Answer:
18,435°
Step-by-step explanation:
tan (α) = 1/3
arctan (1/3) = 18,435 degrees
1/21 would equal x. Hope this helps!
