Answer:
AB = 7√2
Step-by-step explanation:
if a(x1,y1) and b(x2,y2) then

Based on your points and on the formula above AB is:

Just substitute the first equation into the second and solve for x: <span><span>32</span>x=−<span>12</span>x+4⟹2x=4⟹x=2</span><span>Now, since y = 3/2 * x, we have y = 3 and we are done.</span>
