Which is the slope of the line that passes through the points (4, 2) and (6, 7)?

answer: 298143

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

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

other answer is correct. i had used the radius of the radius somehow. a website:
