Question

Which of the following equations represents the line with a slope of negative 1/5 and a y-intercept of negative 11?

Answer 1

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis.

According to the statement data we have:

$m = - \frac {1} {5}\\y = -11$

So, the equation is of the form:

$y = - \frac {1} {5} x-11$

Answer:

$y = - \frac {1} {5} x-11$
