Answer:

[tex]m=20n[/tex]

Step-by-step explanation:

Let

[tex]A(5,100),B(10,200)[/tex]

step 1

Find the slope

The formula to calculate the slope between two points is equal to

[tex]slope=\frac{m2-m1}{n2-n1}[/tex]

substitute the values

[tex]slope=\frac{200-100}{10-5}=20[/tex]

step 2

Find the equation of the line into slope-point

[tex]m-m1=slope(n-n1)[/tex]

with the slope and the point A

[tex]m-100=20(n-5)[/tex]

[tex]m=20n-100+100[/tex]

[tex]m=20n[/tex]
