Line k is defined by y = 6x ＋\( \frac{1}{9} \) . Line j is perpendicular to line k in the xy-plane. What is the slope of line j?

The function h is defined by h(x)= a^x＋b, where a and b are positive constants.The graph of y = h(x) in the xy-plane passes through the points (0, 8) and (2, 32). What is the value of ab?

f(x) = 5x＋b
For the linear function f, b is a constant and f (7) = 35. What is the value of b?

What is an equation of the graph shown?

A botanist wants to plant certain types of oak trees and pine trees in a 600-foot-long row. Each of these oak trees requires 40 feet of space to grow, and each of these pine trees requires 30 feet of space to grow. The equation 40x ＋ 30y = 600 models the possible number of oak trees, x, and pine trees, y, that the botanist can plant. Which graph represents this relationship?
