Answer
Choice C
Work Step by Step
Recall:
The slope-intercept form of a line's equation is $y=mx+b$ where $m$ is the slope and $(0, b)$ is the $y$-itercept (the point where the line passes through the $y$-axis).
The given graph passes through the $y$-axis at $1.$
Hence, its $y$-intercept is $(0, 1)$ and $b=1$.
Among the choices, only Choice C has an equation of a line that has a $y$-intercept of $1.$
