Answer:
y = -7x - 2
Step-by-step explanation:
To write this into an equation, we need to use the y = mx + b formula.
y = mx + b
-30 = -7(4) + b <--- Substitute 4 as x, and -30 as y.
-30 = -28 + b
+ 28 +28 <--- Add 28 on both sides of the equation.
-2 = b
Final equation:
y = -7x - 2
Hello!
The graph, (2/5)^x is an exponential function.
Since there is not a negative symbol in the front of the function, options A and B are incorrect.
For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x.
So therefore, the answer option 4. (Also, I'll post a graph. :))
