Answer:
y=(-1/2)x+6
Explanation:
Start by calculating the slope. Slope = rise/run.
In the equation y=mx+b, m is the slope. This is slope intercept form.
The formula is (y2-y1)/(x2-x1).
Pick 2 points from the graph. Let's use (0,6) and (4,4).
slope = m= (6-4)/(0-4)
slope = m = 2/-4 = -1/2
[This negative slope makes sense because this graph is decreasing - - - as x increases, y decreases.]
The graph shows us the y intercept is 6.
So the equation is y=(-1/2)x+6.
