Find the slope of the line that passes through each pair (1,3) and (1,0)

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

i believe the answers 600m
