Answer:
Slope = -5/2 OR = -2.5
Step-by-step explanation:
Given co-ordinates:
We could easily find the slope through the formulae of slope, that is:
[tex] \rm \: m(slope) = \cfrac{y_2 -y_1 }{x_2 - x_1} [/tex]
According to the question we can identify:
- [tex]\rm (y_2,y_1) = (7,12)[/tex]
- [tex]\rm (x_2,x_1) = (4,2)[/tex]
Plug the values into the slope formulae:
[tex] \rm \: m = \cfrac{7 - 12}{4 - 2} [/tex]
[tex] \rm \: m = \boxed{\cfrac{ - 5}{2}} = \boxed{ - 2.5}[/tex]
Therefore the slope is -5/2 or -2.5.
