Use the two points (4,92) and (1,82) from the scatterplot and the slope formula to find the slope of a linear model (regression line), rounded to three decimal places. show your work. (5 points) using the slope and a point from question (a) to write the equation of the linear model in point-slope form? (5 points) simplify the equation you wrote in problem (b) into slope-intercept form. show your work. (5 points)

a) The slope is : 3.333

b)

c)

Step-by-step explanation:

a) - The formula to calculate the slope is:

- Use the given points to calculate the slope:

b) - The equation of the linear model in point-slope form is:

Where is the slope and are the coordinates of a point.

- Substitute values:

c) - The equation of the linear model in slope-intercept form is:

Where is the slope and is the y-intercept.

- Let's find . Use one of the points given in the problem to solve for :

- Therefore, the equation is:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
