Annette [7]

Answer:

\sf a = \boxed{\bf 1}  \ n+ \boxed{\bf 3}

Explanation:

\sf \underline{rate} \ = \ \sf \dfrac{y_2-y_1}{x_2-x_1} \   = \  \dfrac{rise}{run}  \ = \  \dfrac{11-10}{8-7}   \ = \  \underline{1}

<u>Equation</u>:

\Rightarrow \sf a - a1 = m(n - n1)

\Rightarrow \sf a - 10 = 1(n -7)

\Rightarrow  \sf a = n - 7 + 10

\Rightarrow \sf a = n + 3

3/7 =9/x<br><br><br><br> solve the following proportions ( they are fractions) thanks!
tresset_1 [31]
3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21

and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
