Answer:
y=-1/2x+b
Step-by-step explanation:
we can see that the line is going through (0,9) and the closest point is goes through next is (1,7).
so knowing that y=mx+b, we can plug in numbers to this equation.
take on of the points, and find the slope. the slope is -1/2.
so we would plug in one of our points plus the slope into our equation:
7=-1/2(1) +b
now we do the algebra and find that 7 1/2 =b.
so now the equation is y=-1/2x+b.
