19a: The constant of propotionality is 2, it's the slope of the graph.
19b. The equation is y=2x
Answer:
Step-by-step explanation:
F(x)= 2x+8 and g(X)=5.
(g o f)(3) = g(f(3))
but f(3) = 2(3)+8 = 14
(g o f)(3) = g(f(3)) = g(14) = 5

The general form for a straight line is y = mx + c where m is slope and c is y-intercept.
Two lines are perpendicular when the product of their slopes = -1
Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2
So a line perpendicular to the given and has the same y-intercept is
y = (-7/3) x - 2
