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 the coefficients as integers, proper fractions, or improper fractions in simplest form.

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 the coefficients as integers, proper fractions, or improper fractions in simplest form.

Answer

Explanation:

Step1: Identify the two - yellow points

Let the two yellow points be $(x_1,y_1)=(20,10)$ and $(x_2,y_2)=(60,80)$.

Step2: Calculate the slope $m$

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. So, $m=\frac{80 - 10}{60 - 20}=\frac{70}{40}=\frac{7}{4}$.

Step3: Use the point - slope form to find the equation

The point - slope form is $y - y_1=m(x - x_1)$. Using the point $(20,10)$ and $m = \frac{7}{4}$, we have $y-10=\frac{7}{4}(x - 20)$.

Step4: Convert to slope - intercept form

Expand the right - hand side: $y-10=\frac{7}{4}x-35$. Then, add 10 to both sides to get $y=\frac{7}{4}x - 25$.

Answer:

$y=\frac{7}{4}x - 25$
