Question

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

Answer 1

Answer:

slope of a trend line that passes through the points (1, 3) and (10, 25) is  $\frac{22}{9}$

Step-by-step explanation:

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

$\text{Slope}(m) = \frac{y_2-y_1}{x_2-x_1}$

Given the two points:

$(1,3)$ and $(10, 25)$

Substitute these points in the given formula we have;

$m = \frac{25-3}{10-1}$

Simplify:

$m = \frac{22}{9}$

Therefore, the slope of a trend line that passes through the points (1, 3) and (10, 25) is  $\frac{22}{9}$

Answer 2

Using y1-y2 divided by x1-x2, 25-3=22 and 10-1=9 22/9 can be written as a mixed number (2 4/9) kept the same or written as a decimal, (2.4).
