Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1). y + 1 = -2(x – 5) y – 1 = -2(x – 5) y – 5 = -2(x + 1) y -5 = -2(x – 1)

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.  

We will substitute and .

This is the equation of the line with slope -2 that passes through (5,-1).

The correct option is:  B. 11

Explanation

In the given scatter plot, the number of computers are shown across the y-axis.

Only one point is lying on the line y=6 and all other points are above that y=6 line. That means, only 1 office had 6 computers.

As there were total 12 different offices, so the number of offices that had more than 6 computers will be: (12 - 1) = 11
