Question

Only answer if your 100% sure What equation is shown in the graph?

Answer 1

(0,2) and (1,1)
slope = (2 - 1)/(0 -1) = -1
y intercept b = 2
equation
y = -x + 2

answer
equation
y = -x + 2

Answer 2

Slope is -1 because from (0,2) to (1,1), that's m = slope = ( rise ) / ( run ) = ( 1 - 2 ) / (1 - 0) = -1 / 1 = -1

And y-intercept is y=2 at x=0, so b = 2

Putting it together:

y = mx+b

y = (-1)x + (2)

Final answer: y = -x + 2
