Question

Using the given graph which of the following could be the equation of line $L_2$.

• A. $y=x-1$
• B. $y=x-2$
• C. $y=x+1$
• D. $y=x+2$

Answer 1

The correct option is C

$y=x+1$

By observing the graph the y-intercept of $L_2$ is 1.

The eqution of $L_2$ is in the form $y=mx+c$

or $y=mx+1$

Hence by observing the y-intercept of the given equations we can deduce $L_2$ has the equation $y=x+1$

Hence (C).
