Answer:
\bold{\text{Slope (m)}=(1)/(4)}

Step-by-step explanation:

A linear equation is of the form: y = mx + b where

  • m is the slope
  • b is the y-intercept (where it crosses the y-axis)

x + 4y = 16

4y = -x + 16


y = -(1)/(4)x+(16)/(4)


y=-(1)/(4)x+4

The y-intercept (b) = 4

Next, find the slope given point (4, 5) and b = 4


y=mx+b\\\\5=m(4)+4\\\\1=4m\\\\(1)/(4)=m\\\\\\\\\large\boxed{Slope (m)=(1)/(4)}
