Which function represents a line with a slope of −4 and a y-intercept of −2? a) y = 4x − 2 b) y = −4x + 2 c) y = −4x − 2 d) y = −2x − 4

C)

Step-by-step explanation:

The general equation of a line in the xy plane is as follows:

where is the slope of the line, and is the intercept with the y axis.

In this case we want a line with a slope of -4, therefore:

and we also want a y-intercept of -2, so:

Substituting in the general equation of the straight line:

⇒

wich is option C
