Question

PLEASE HELP! WILL GIVE BRAINLIEST ANSWER + 100 POINTS!!

(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, rounded to three decimal places. 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.

Answer 1

A) You would use the two points that are closest to the graphed line

(2,7) and (8,13)

B) Slope = change in Y over the change in X:

Slope = (13-7) / (8-2) = 6/6 = 1

Slope = 1

c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.

Equation is: y-7 = x-2

d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.

To isolate Y add 7 to both sides:

y = x +5

Answer 2

Step a is (2,7)/(8,13).

Step b is 1

Step c is y-7 = x-2

Step d is y = x +5
