Question

Задайте формулой функцию являющиюся прямой пропорциональностью если её график проходит через точку м (3;-2) помогите плизззз

Answer 1

Y=kx,  K=y /x =-2\3 => y(x)=-2/3x

Answer 2

Finding the Formula for a Direct Proportion

To find the formula for a direct proportion, we need to determine the relationship between two variables that are directly proportional. In this case, we are given that the graph of the function passes through the point (3, -2).

Let's assume that the formula for the direct proportion is y = kx, where y represents the dependent variable, x represents the independent variable, and k is the constant of proportionality.

To find the value of k, we can substitute the given point (3, -2) into the equation and solve for k.

Substituting x = 3 and y = -2 into the equation y = kx, we get:

-2 = k * 3

Solving for k, we divide both sides of the equation by 3:

k = -2/3

Therefore, the formula for the direct proportion is:

y = (-2/3)x

This formula represents a straight line that passes through the point (3, -2) and is a direct proportion between x and y.
