We have:

We know. The line <em>l</em> passes throught the point (9, -7). Substitute the coordinates of the poin to the equation of line<em> l </em>:


Answer: 
Answer:
12xy
Step-by-step explanation:
Product of [x y] [1 2] is
(xy)×(12)=12xy
The slope in y = mx + b form will be in the m position (the number before the x)
y = 2/5x ? 2..here the slope is 2/5.....a perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign.
2/5.....flip it....5/2...change the sign...-5/2...so we need a slope of -5/2.
answer C......y = -5/2x + (-3)
Answer:

Step-by-step explanation:
Hello, first of all, we will check if we can factorise the polynomials.




Now, let's compute the product.

So the correct answer is the first one.
Thank you.
