The slope of the given linear equation is 1/3 and the y-intercept will be 5/6. Then the correct option is D.
<h3>What is the slope?</h3>
The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
Identify the slope and y-intercept of the line whose equation is given. Write the y-intercept as an ordered pair.
The linear equation is given below.

Then the slope of the equation will be 1/3.
And the y-intercept will be 5/6.
