Answer:
-2.1
Step-by-step explanation:
Rewriting in intercept form
4x+6y= 3 becomes
y= 4x/6 + 3 /6 = ⅔x + ½
it's m = 2/3
for the second line
6x + 9y = 7
y= 6x/9 + 7/9 = ⅔x +7/9
it's m = 2/3
so the two lines are parallel..

Answer: Third option

Step-by-step explanation:
We have the vector u and the vector v. We must perform the operation
.
To perform this operation multiply the vector u by -1 and multiply the vector v by -1.
If u = (-5,6)
So
-1u = (5, -6)
If v = (7, -3)
So
-1v = (-7, 3)
Then the sum of both vectors is done by adding the components of u with the components of v.
