Answer:
-3
Step-by-step explanation:
2a - 6 = 4a
subtract 2a giving you -6 = 2a
divide by 2 from both sides so that a will be by itself
giving you -6 ÷ 2 = a
-6 ÷ 2 = -3
so a = -3
For this case we have that by definition, the slope of a line is given by:

Where:
and
are two points through which the line passes.
According to the image we have:

Substituting we have:

Thus, the slope of the line is:
