Answer 1

Answer:

Step-by-step explanation:

I'm not exatcly sure what is meant by magnitude but if it is the slope it is simply -7 if it is asking about the actual magnitude or length of the vector then we use pthagorean theorum which is:

$c^{2} =a^{2} +b^{2}$

when adjusted to solve for the  answer is

$c = \sqrt{a^{2}+b^{2}\\}$

which is c = sqrt (1^2) + (-7)^2 = $\sqrt{50}$ would be the exact answer
