Answer: It would be y-3=2(x-10)

Step-by-step explanation:

Since Alejandra's teacher said that it had a slope of 2, in the equation y-y1=m(x-x1), the m, is the slope, therefore, the m is a slope of 2.

Hope this helped.

Ne4ueva [31]

Answer:

8=7t

Step-by-step explanation:

The table given shows that both variables are directly proportional to each other. That is, as s variable increases, y variable also increases.

Equation to represent this direct proportion would be:

8=kt,

where, k = constant of proportionality.

Let's find k from the table given.

Let's use any pair values of of s and t given in the table. Say, s = 21, t = 3

8=kt

21=k3

Divide both sides by 3

21/3= k3/3

7=k

k=7

Plug in k = 3 into :

8=7t

Hope this work!
