Answer:
Option 3rd is correct
the slope of the line passing through (1, 2) and (3, 8) is, 3
Step-by-step explanation:
Using slope formula for two points:
\(\text{Slope} = \frac{y_2-y_1}{x_2-x_1}\) .....[1]
As per the statement:
Given that:
A line passing through (1, 2) and (3, 8).
Substitute these points in [1] we have;
\(\text{Slope} = \frac{8-2}{3-1}\)
⇒\(\text{Slope} = \frac{6}{2}\)
Simplify:
\(\text{Slope} = 3\)
Therefore, the slope of the line passing through (1, 2) and (3, 8) is, 3
