The complete graph of the function f and a table of values for the function g are shown above. The maximum value of f is k. What is the value of g(k)?

In the xy-plane, the point (p, r) lies on the line with equation y = x + b, where b is a constant. The point with coordinates (2p, 5r) lies on the line with equation y = 2x + b. If p ≠ 0, what is the value of $r over p$ ?

If we have coordinates of two points on a line, then we can use the slope formula to determine that line's slope. m = (y₂-y₁) / (x₂-x₁), or the ratio of the change in the y values and the x values, is the slope formula. 'x₁' and 'y₁' are the coordinates of the first point. The second points have the coordinates x₂ and y₂. If you have two points, you can always calculate the slope of a line. If you don't have access to two points, you can locate two points on the graph and use those to calculate the slope.
¶Observe the following helpful information:
- m = slope
¶-Rise = the difference between the y-values (y₂- y₁), where (x₁, y₁) = point 1 and (x₂, y₂) = point 2.
Run is equal to the difference between x-values (x₂ - x₁).

In the xy-plane, the point (p, r) lies on the line with equation y = x + b, where b is a constant. The point with coordinates (2p, 5r) lies on the line with equation y = 2x + b. If p ≠ 0, what is the value of $r over p$ ?
