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:
[tex]\text{Slope} = \frac{y_2-y_1}{x_2-x_1}[/tex] .....[1]
As per the statement:
Given that:
A line passing through (1, 2) and (3, 8).
Substitute these points in [1] we have;
[tex]\text{Slope} = \frac{8-2}{3-1}[/tex]
⇒[tex]\text{Slope} = \frac{6}{2}[/tex]
Simplify:
[tex]\text{Slope} = 3[/tex]
Therefore, the slope of the line passing through (1, 2) and (3, 8) is, 3
