It will be D. 168 because 7 times -4 = -28 then you times -28 with -6 and it equals 168.
They are not parallel because the slopes are different (slope of 4 and slope of 0.25)
Neither are they perpendicular. If they were then m1*m2 ( the product of their slopes) would be -1 ). The product of these slopes = 4*0.25 = 1)
So choice A is the correct one.
Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.
Yes he is correcct because 4/8 and 1/2 is the same thing
