Can someone please help, ty!!

Look where the graph crosses the vertical y axis. This point is the y intercept.

In this case, the y intercept is located at (0, -1)

You start at the origin (0,0) and move down 1 unit to get to (0, -1)

Side note: The equation of this line is y = 2x-1

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
