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: Encontrar la pendiente
La fórmula de la pendiente \(m=\frac{y_2 - y_1}{x_2 - x_1}\). Los dos puntos amarillos son \((2,1)\) y \((7,9)\). Entonces \(m=\frac{9 - 1}{7 - 2}=\frac{8}{5}\)
Step2: Encontrar la ecuación en forma pendiente - intersección
La forma pendiente - intersección es \(y=mx + b\). Usamos el punto \((2,1)\) y \(m = \frac{8}{5}\). Sustituimos: \(1=\frac{8}{5}(2)+b\). Resolvemos para \(b\): \(1=\frac{16}{5}+b\), \(b=1-\frac{16}{5}=\frac{5 - 16}{5}=-\frac{11}{5}\)
