What is the slope of the line y+4 = 3(x+6)
Akimi4 [234]

Answer:

3

Step-by-step explanation:

First you gotta take the equation and bring it to the following form:

y = ax + b

The slope of the line is the coefficient of x, a.

In other words:

y + 4 = 3(x + 6) \\ y + 4 = 3x + 18  \\ y = 3x + 18 - 4 \\ y = 3x + 14

So, as we can see, the number infront of x is 3. That is to say that the slope of this line is equal to 3.
