.
Work Step by Step
Comparing to $y=mx+b,$
the y-intercept is $4$,
the slope is $m=-2=\displaystyle \frac{-2}{1}\quad=\frac{\text{change in y}}{\text{change in x}}$.
To obtain a second point, starting with $(0,4)$,
change x by $1$, y by $-2\quad\rightarrow\quad(1,2)$.
Draw a line through the two points.
