What is the slope of the line that passes through (-2, 7) and (4.9)? Type a numerical answer in the space provided. If necessary, use the key for a fraction bar. Do not include spaces in your answer.

1/3

Step-by-step explanation: hope this helps!

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
