Answer
Graph B
Work Step by Step
We are given the graph for $y=f(x)=5x$.
We can plug in x=0, to find the y-intercept of the equation.
$f(0)=5\times0=0$. Therefore, the y-intercept of $f(x)=5x$ is 0.
For $f(x)=5x+3$, the y-intercept is $f(0)=5\times0+3=3$.
Graph B, shows that the line crosses the y-axis at (0,3) and is the only graph whose line has a y-intercept of 3. Therefore, the line in Graph B is shifted up 3 units compared to the original graph.
