City officials conclude they should budget s million dollars for a new library building if the population increases by p thousand people in a ten-year census. The formula s=2+13(p+1)13 expresses the relationship between population and library budget for the city. How much can the population increase without the city going over budget if they have $5 million for a new library building?

(B) and (C)
Step-by-step explanation:
The slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope can be calculated by finding the ratio of the "vertical change" to the "horizontal change" between two different points on a line.
Thus, from the definition of the slope, we have
(A) Slope=Change in the dependent variable relative to change in the independent variable.
which is correct expression for the slope.
(B)![S=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](/tpl/images/0428/1362/30ab0.png)
which is the formula for the slope.
Now, the given option is![S=\frac{x_{2}-x_{1}}{y_{2}-y_{1}}](/tpl/images/0428/1362/c65b9.png)
which is incorrect.
(C) The slope of is given as rise over run that is
but the given option is
which is incorrect.
(D) The slope formula is given as:
which is the correct expression.
Therefore, the options are (B) and (C) which are incorrect expressions for slope
