B is the answer I did that last week at my school
Answer:
Not sure what they want when they say evaluate it but the answer would be -12.
Step-by-step explanation:
You distribute the 6, so you would multiply 6 x 7 then keep the minus sign and multiply 6 x 9. So you would have 42 - 54, and just subtract which = -12
Step1- substitute 1 into the y
= -3x-4 x 1=14
=-3x -4=14
=-3x=14+4
=-3x=18
X=18/-3
X=-6
Answer:
BOTH THE QUESTIONS ARE SAME!!
When finding a perpendicular slope, you need to <u>change the signs</u> and <u>flip the reciprocal</u>
The answer to your question is:
m = -2
