Which proportion could be used to show the slope of line VX is equal to the slope of line XZ?

• $\frac{1-\left(-5\right)}{1-\left(-2\right)}=\frac{1-3}{1-\left(-5\right)}$

• $\frac{1-\left(-5\right)}{1-\left(-2\right)}=\frac{5-1}{3-1}$

• $\frac{-2-\left(-5\right)}{-2-1}=\frac{5-1}{3-1}$

• $\frac{1-\left(-2\right)}{1-\left(-5\right)}=\frac{3-1}{5-1}$
