Question
what is the equation of the trend line in the scatter plot?
use the two yellow points to write the equation in slope - intercept form. write any coefficients as integers, proper fractions, or improper fractions in simplest form.
Step1: Calcular la pendiente \(m\)
La fórmula de la pendiente es \(m=\frac{y_2 - y_1}{x_2 - x_1}\). Tomando los puntos \((2,0)\) y \((6,8)\), entonces \(m=\frac{8 - 0}{6 - 2}=\frac{8}{4}=2\).
Step2: Encontrar la ecuación en forma pendiente - intersección \(y = mx + b\)
Sustituir \(m = 2\) y el punto \((2,0)\) en la ecuación \(y=mx + b\). Tenemos \(0=2\times2 + b\), entonces \(b=- 4\).
