What equation is shown in the graph?
2 answers:
(0,2) and (1,1)
slope = (2 - 1)/(0 -1) = -1
y intercept b = 2
equation
y = -x + 2
answer
equation
y = -x + 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
