What is the slope of a trend line that passes through the points (1, 3) and (10, 25)?

slope of a trend line that passes through the points (1, 3) and (10, 25) is  

Step-by-step explanation:

Formula of slope(m) for two points is given by:

Given the two points:

and

Substitute these points in the given formula we have;

Simplify:

Therefore, the slope of a trend line that passes through the points (1, 3) and (10, 25) is  

y + 11 = (1/4)(x + 16)

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
