Answer:
A. y=-2x + 8
Step-by-step explanation:
The slope-intercept formula is written as y=mx+b, where m is the slope and b is the y-intercept.
b can be easily found on the graph, as the point (0,8) is where the line crosses the y-axis, so b=8.
The slope can be found using the slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
We can take either points as the first, and we'll reach this result.
[tex]\frac{-4-8}{6-0} = \frac{-12}{6} = \frac{-2}{1}[/tex]
This means that the slope is -2 and the y-intercept is 8
So the final equation is choice (a.)
