the magnitude of the vector by pythagorean theorem
r = √( (-10)^2 + (3)^2 ) = √109
magnitude = √109 units
the direction angle between vector and x-axis is
tan^(-1)(3/10) = 16.699
so the direction is approximately 16.7 degrees north of west

If one were to put the y value into the equation, they could find out what x is for a certain value of y. putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
