Question

Show that line passing through points (3,-2) and (-4,-2) is a horizontal line​

Answer 1

Step-by-step explanation:

horizontal lines will have a gradient(m) of 0

so if m=0 , the line is horizontal

formula to find m:

m=y2-y1 / x2-x1

insert coordinates into formula

$m = \frac{ - 2 - ( - 2)}{ - 4 - 3} \\ \\ m = \frac{ - 2 + 2}{ - 7} \\ m = \frac{0}{ - 7} \\ m = 0$

As m=0 , therefore it is a horizonta line.

hope this helps..
