You need to see what you need to convert and how you need to convert it, do you need to divide to find out how many it goes in? Questions like that.

Use slope formula: y2-y1/x2-x1

XZ: -5/9
YZ: 2/7
XY: -7/2

XYZ is a right triangle because two of these slopes have a product of -1.

(YZ and XY does). We are all busy these days.
