I’m not sure if that picture worked or not but it’s a question from my textbook that was asking what factors would cause velocity of blood in an artery to decrease. It says in the answer at the bottom that apparently a lower pressure would Cause this, but I thought pressure and velocity were inversely related because of Bernoulli’s law?

The Bernoulli equation uses the energy of the fluid before and after traveling through different cross sectional areas. This is a link to a good explanation of the principle. In general, when a fluid's speed increases, its pressure decreases, that's why planes can fly so well, the lower pressure, faster moving air above the wing causes a net upward force called lift.
