2. A linear model for the data in the table is shown in the scatter plot. x 1 2 4 5 6 7 8 9
y 25 24 15 12 11 13 6 4

(a) Which two points should you use to find the equation of the model? Explain.

(b) Use the two points you chose in Part (a) to find the slope of the linear model, leaving your slope in fraction form. Show your work.

(c) What is the equation of the linear model in point-slope form?

(d) Rearrange the equation you wrote in Part (c) into slope-intercept form. Show your work.

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
