$x+y=49\\\underline{x-y=\dfrac{1}{2}}\\2x=49.5\\x=24.75\\\\24.75+y=49\\y=24.25$

Those numbers are 24.75 and 24.25.

Answer:

To find m ( slope) we'll use the Slope Formula:

$\boxed{\sf{Slope\:(m)}=\cfrac{y_2-y_1}{x_2-x_1}}$

<u>Subtract the numbers:-</u>

$\sf 7. \:m=\cfrac{4-2}{6-5} =\boxed{2}$

_______________

$\sf 8.\: m=\cfrac{-1-3}{2-6} =\boxed{1}$

_______________

$\sf 9.\: m=\cfrac{-4-(-2)}{3-1} =\boxed{-1}$

_______________

$\sf 10.\: m=\cfrac{0-3}{0-(-3)} =\boxed{-1}$

_______________

$\sf 11.\:m=\cfrac{4-2}{3-1} =\boxed{1}$

_______________

$\sf 12.\: m=\cfrac{1-7}{2-5} =\boxed{2}$

_______________

$\sf 13.\:m=\cfrac{11-9}{1-(-4)} =\boxed{\frac{2}{5}}$

_______________

$\sf 14.\:m=\cfrac{2-3}{3-5} =\boxed{\frac{1}{2}}$

_______________

$\sf 15.\: m=\cfrac{11-5}{2-9} =\boxed{-\frac{6}{7}}$

_______________

$\sf 16.\: m=\cfrac{-7-\left(-6\right)}{8-13}=\boxed{\frac{1}{5}}$

_______________

$\sf 17.\: m=\cfrac{4-4}{6-1} =\boxed{0}$

_______________

$\sf 18. \: m=\cfrac{2-(-7)}{5-5}=$

↑ Undefined
