Passes through: (4,5) slope: 3/2

y = (3/2)x - 1

Step-by-step explanation:

since the slope is 3/2, we already have y=(3/2)x + b. plug in the point (4,5) to get 5= (3/2)*4 + b, or 5=6+b, subtract 6 from both sides to get b=-1. so the equation is y=(3/2)x - 1

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
