What is the equation of the graph?




y = x + 1

y = x

y=x−1

y = 2x

Answer 1

It’s x+1. The slope is 1, so the x doesn’t change. The line starts 1 higher than the x axis so add 1.

Answer 2

(0, 1) and (-1, 0)

slope m = (1 - 0)/(0 +1) = 1

y intercept b = 1

Equation: y = mx + b where m = 1 and b = 1

so equation y = x + 1

Answer

y = x + 1
