Answer:
the slope of W is less than the slope of Z
Explanation:
Function Z
find slope take two points (0,15.8) (1,15.76)
m=y2-y1/x2-x1
m=(15.76-15.8)/1-0
m=-0.04
the equation for function z : y=-0.04x+15.8
slope of W=-0.0625 which is less than -0.04
y intercept pf W=30, is greater than the y intercept of Z=15.8
