Issof claims that the scale factor is 1/2. which statement about his claim is correct

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.

How can you find the magnitude of a vector, v = < x, y > , where the horizontal change is x and the vertical change is y?
