we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

Step 1
<u>Find the slope of the given line</u>
we have

Solve for y
Divide by
both sides


the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have



substitute the value of m1

therefore
<u>the answer is</u>
the slope is 
Answer:
It is going to be C.9 hope this help hopefully not late. :D
Step-by-step explanation:
Its like a train so (2x3)+8x(7x-2)= your answer but you can solve it in a calculator :D
I think it will be 2:4. 2X9=18 so u × 4×9=36 so its 18 to 36
