What is the slope of the line on the graph below

1/3

Step-by-step explanation:

Given the points you just use rise over run, meaning to get from one point to the next you go up one y value and to the right 3 x values.

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
