Question

what is the equation of the trend line in the scatter plot? use the two orange points to write the equation in slope - intercept form. write any coefficients as integers, proper fractions, or improper fractions in simplest form.

Explanation:

Step1: Encontrar la pendiente \( m \)

La fórmula de la pendiente es \( m=\frac{y_2 - y_1}{x_2 - x_1} \).
Tomando los puntos \((4,8)\) y \((7,5)\), se tiene:
\( m=\frac{5 - 8}{7 - 4}=\frac{-3}{3}=-1 \)

Step2: Encontrar la ecuación en forma pendiente - intersección \( y = mx + b \)

Sustituir \( m=-1 \) y el punto \((4,8)\) en \( y = mx + b \):
\( 8=-1\times4 + b \)
\( 8=-4 + b \)
\( b=8 + 4=12 \)

Answer:

\( y=-x + 12 \)
