Answer: 4
The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given
Flip the sign to get -1/4 turn into +1/4 or just 1/4
Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.
Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.
There is no picture, but you would substitute the first number for the x and the second for the y
To combine like terms, check if there are any terms just like the first one, and we see 6xy. 9xy + 6xy = 15xy. So that is one term. Now I would see if the second term has any terms like the first one, and we see -3y. So -3y + (-3y), we would get -6y. That means our polynomial is now 15xy - 6y, and because this has two terms, it is a binomial. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer. (Not necessarily mine). Thanks, it really helps!
