Question

PLEASE HELPPPPPP!!!!!!!!

Answer 1

Step-by-step explanation: The answe is y= 3 because first of all to find the answer for this question you need to divide first x and then y like this steps that i did that are shown below.

21/7=3

15/5=3

12/4=3

so hopefully 3 is the correct answer and have a great day everyone and if you want please give me brainliest.

Answer 2

Answer:

$\sf y=\dfrac{1}{3}x$

Step-by-step explanation:

First find the slope:

$\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{4-5}{12-15}=\dfrac{1}{3}$

Use the point-slope form of linear equation:  $\sf y-y_1=m(x-x_1)$
(where m is the slope and (x₁, y₁) is a point on the line)

with the found slope and one of the points:

$\begin{aligned}\sf y-y_1 &=\sf m(x-x_1)\\\\\implies \sf y-4 &=\sf \dfrac{1}{3}(x-12)\\\\\sf y-4 &=\sf \dfrac{1}{3}x-4\\\\\sf y &= \sf \dfrac{1}{3}x\end{aligned}$
