Question

As well as this I need help last one tho i think

Answer 1

y=-1/2x+b

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.
