Set up a proportion, cross multiply, and solve.
3(7.2) = 4(x)
21.6 = 4x
5.4 = x
Answer:
b number is a solution of in equality
Step-by-step explanation:
Its Undefined.
Reason
Slope (m) = y2 - y1/(x2-x1)
= 3-(-6)/(12-12)
=9/0
Undefined
You can clearly see this from the points. The x value has 2 different values for y... Which Makes the points not that of a function.
