Write an equation of the line that passes through the points (5, -7) and (3, -1).

y = -3x + 8

Step-by-step explanation:

I like to recommend this particular method for finding the slope of a  line through two given points:

Notice that if we move from (3, -1) to (5, -7), the horizontal distance covered (the "run") is 2 and the vertical change (the "rise") is -6.  Thus, the slope is m = rise / run = -6 / 2, or -3.

Starting with y = mx + b, replace y with -7 and x with 5, and m with -3:

-7 = -3(5) + b    ...  we must find b.

-7 = -15 + b    yields b = 8

and so the equation of this line is y = -3x + 8.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
