The function g is defined by g(x)=ax−7, where a is a constant. Find a, if the graph of g passes through the point ( 1/3,−2).
1 answer:
Answer:
a = 15
Step-by-step explanation:
g(x) is the same thing as "y". Our point gives us an x and y value, so we will sub those into the equation and solve for a:
-2 = a(1/3) - 7 and
-2 = 1/3a - 7 and
5 = 1/3a so
a = 15
