Find the value of k so that the slope of the line through (2,-k) and (-1,4) is -3

Alona [7]

K is equal to 3. to find this i used the slope formula y2-y1/x2-x1. 4-k/-1-2
-1-2=-3 so that means that 4-k has to equal 1. 4-3=1
k=1

Find the slope please

scoray [572]

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

May I have brainliest please? :)

Jordan swam 4 laps. Each lap is 100 meters. Jordan’s average speed for the first 3/4 of his swim was 40 meters per minute, and f

Leya [2.2K]

Answer/step-by-step explanation:

The 300/40 comes from the fact that ¾ of a 400 meter swim is 300 meters, and if you want to know how long he took to do that, you need to divide by the speed, 40 meters per minute (meters divided by meters per minute = minutes). Likewise with the 100/35—that’s the last 100 meters he swam, at the slightly slower speed.

Just to bring it all the way home, average speed is total distance divided by total time. that the total distance is 400 meters. You know the total time is 300/40 + 100/35. Average speed, then, is:

Average Speed: $= \frac{400}{\frac{300}{40} +\frac{100}{35} }$

Round: 39 meters per minute

I think if wrong I'm sorry
