Find the slope of the secant line between the values x1 and x2 for the function y=f(x)

i belive those are the ones that are under 90 degreese.

answer: 10 meter

step-by-step explanation:

need details

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
