Question

Two points on a line are (3, 6) and (4, 9). What is the slope of the line?

Answer 1

Answer:

slope of line= 3

Step-by-step explanation:

slope of line= $\frac{y1 - y2}{x1 - x2}$

(X₁, Y₁)= (4, 9)

(X₂, Y₂)= (3, 6)

* The order of which one is the first coordinate or second does not matter. Just ensure that if you let the x-coordinate of 1 point to be X₁, the y-coordinate of the same point has to be Y₁.

Thus, slope of line

$= \frac{9 - 6}{4 - 3} \\ = \frac{3}{1} \\ = 3$
