Answer:
b.y= -1/2x+2
Step-by-step explanation:
The graph is a line then it’s equation has this form y = ax + b where a the slope and the y-intercept
the y-intercept b = 2 cause the line intersects the y-axis at the point (0 , 2)
[tex]a=\frac{0-2}{4-0} =\frac{-2}{4} =\frac{-1}{2}[/tex]
Finally,
y = ax + b
= (-1/2)x + 2
