The slope of a line with points (8, 42) and (3, 25) is -17/5

<h3>The first step in graphing data in a scatter plot</h3>

To graph a scatter plot, we simply determine the axis to plot each of the corresponding data

The axes are simply x and y axes

Hence, the first step in graphing data in a scatter plot is (d) Determine which axis corresponds to which data.

<h3>The slope of the line</h3>

The points are given as:

(8, 42) and (3, 25)

The slope of the line is calculated as:

m = (y2 - y1)/(x2 - x1)

This gives

m = (25 - 42)/(3 - 8)

Evaluate

m = -17/5

Hence, the slope of a line with points (8, 42) and (3, 25) is -17/5

We know that angle MKJ is comprised of angle MKL and angle LKJ. That means if we add MKL and LKJ, we should get 80 degrees, which is the measure of angle MKJ.

$MKL + LKJ= MKJ \implies \\ 2x+10+3x-5=80 \implies \\ 5x+5=80 \implies\\ 5x=75 \implies \\ x=15$

So, we know that our x is 15. That is not enough to tell whether KL is an angle bisector, because we have to evaluate both MKL and LKJ with x=15, so:

$MKL=2(15)+10 = 40\\ LKJ=3*15-5=40$

So we see that these two angles are actually bisectors, and the third question best describes this phenomenon.

Answer:

Eli has to run for 2.25 minutes at this pace to win the bet.

Step-by-step explanation:

At his last track meet, Eli ran the 400-meter dash in 54 seconds.

So, the speed of Eli's run is $\frac{400}{54} \times 60 = 444.44$ meters per minute.

Now, if Eli is determined to run a whole kilometer with the same speed, then it will take Eli to run 1 kilometer within $\frac{1000}{444.44} = 2.25$ minutes.
