How do you write a equation from two data points?
To write an equation from two data points, first identify the coordinates of the points, typically represented as (x₁, y₁) and (x₂, y₂). Calculate the slope (m) using the formula ( m = \frac{y₂ - y₁}{x₂ - x₁} ). Then, use the slope-intercept form ( y = mx + b ) to find the y-intercept (b) by substituting one of the points into the equation. Finally, write the complete equation of the line.
How do you write an equation to represent a proportional relationship?
To write an equation representing a proportional relationship, you start with the general form ( y = kx ), where ( k ) is the constant of proportionality. This equation indicates that ( y ) varies directly with ( x ); as ( x ) increases or decreases, ( y ) does so by the same factor determined by ( k ). To find ( k ), you can use known values of ( x ) and ( y ) from the relationship.
An example of a problem that needs to be solved?

How do you write an equation if x and y vary directy?
y = kx for some non-zero constant k that you then need to find.
Find a number whose product with 8 is the same as its sum with 49?
Call your number "x", write an equation, and solve it: 8x = x + 49 7x = 49 x = 7
