Answer:

slope is rise over run in other words it's the difference from one point to the other in y/x so you go from one point and count how many tiles up then how many times left or right. the slope of this line is 4

Start at the first point which in this case is (-1,-4). then go up 3 (since thats where the next point is) and over to the right 1 (since thats where the point is lol). since the line is positive, then the answer is 3/1 or 3.

The midpoint of the line segment from upper p 1p1 to upper p 2p2 is left parenthesis negative 1 comma 5 right parenthesis(−1,5).

aliya0001 [1]

The coordinates of the second point are (2, 4).

The midpoint formula is:
$m=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Substituting our information, we have:

$(-1, 5)=(\frac{-4+x_2}{2},\frac{6+y_2}{2})$

This means that
$-1=\frac{-4+x_2}{2} \text{ and } 5=\frac{6+y_2}{2}$

Multiply both sides of both equations by 2 to cancel it:
$-1\times2=(\frac{-4+x_2}{2})\times2 \text { and } 5\times2=(\frac{6+y_2}{2})\times2
\\
\\-2=-4+x_2 \text { and } 10=6+y_2
\\-2+4=-4+x_2+4 \text { and } 10-6=6+y_2-6
\\2=x_2 \text{ and } 4=y_2$

This gives us our coordinates (2, 4)
