What is the slope of the blue line

Hello there!

To find the slope of a line, we need to know at least two points contained in the graph of the line.

The slope of a line passing through the points and is given by the formula: .

As we can see on the graph, two points contained on the line are and .

Using the formula above, we get that:

Subtract the values on both numerator and denominator of the fraction

This is the slope of this line we were looking for and is the answer contained on the 4th option.

a - base

b - exponent
