The Domain is the first number of the pair
D= -7, -6, -5, -4
The Range is the second number of the pair
R= 5, 1, 0, when a number repeats like the number one you can put it once.

On a number line, the directed line segment from q to s has endpoints q at –14 and s at 2. point r partitions the directed line

The coordinates of point r(-8,0).

<h3>What is midpoint formula in coordinate geometry?</h3>

The coordinates of the point r(x,y) which divides the line segment joining the points p(x_{1},y_{1}) and q(x_{2},y_{2}) internally in the ratio :m_{1}m_{2} are

\left(\frac{m_{1}x_{2}+ m_{2}x_{1} }{m_{1}+m_{2}  } ,\frac{m_{1}y_{2}+ m_{2}y_{1} }{m_{1}+m_{2}  }\Rifgt)

Given that,

Two end points on the line q(-14,0) and s(2,0). point r(x,y) is the partition of the line segment from q to s in a ratio 3:5

m_{1} = 3 and m_{2} = 5

By using the midpoint formula

\left(\frac{m_{1}x_{2}+ m_{2}x_{1} }{m_{1}+m_{2}  } ,\frac{m_{1}y_{2}+ m_{2}y_{1} }{m_{1}+m_{2}  }\Rifgt)

\left(\frac{3(2)+ 5(-14) }{3+5  } ,\frac{3(0)+ 5(0) }{3+5  }\Rifgt)

\left(\frac{-64}{8  } ,\frac{0 }{8  }\Rifgt)

\left(-8 ,0\Rifgt)

Hence, The coordinates of point r(-8,0).
