Dan's data
A What is the slope of the line?
8
What does the slope represent in the situation?
What is the intercept
D. What is the equation for the line?
.

i think that you should ask google for the answer to that problem because if we don't know it google does

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

jbankston is right, use thhe link and you should find the answer.

what's the question here?
