Question

Which function represents a line with a slope of −4 and a y-intercept of −2?

Answer 1

The correct answer is C) y = -4x - 2.

Answer 2

Answer:

C) $y = -4x - 2$

Step-by-step explanation:

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

$y = mx + b$

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

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

$m = -4$

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

$b = -2$

Substituting in the general equation of the straight line:

$y = mx + b$

⇒$y = -4x-2$

wich is option C
