Answer:
slope of line= 3
Step-by-step explanation:
slope of line= [tex] \frac{y1 - y2}{x1 - x2} [/tex]
(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
[tex] = \frac{9 - 6}{4 - 3} \\ = \frac{3}{1} \\ = 3[/tex]
