Part a)

we know that

to find the equation of the line, I will use the two points that are closest to the line

Let

A(1,14)

B(7,7)

Part b)

Find the slope

we know that

the formula to find the slope between two points is equal to

m=(y2-y1)/(x2-x1)

substitute

m=(7-14)/(7-1)

m=(-7)/(6)

m=-7/6=-1.167

the answer part b) is

the slope is m=-7/6=-1.167

Part c)

we know that

the equation of the line in point slope form is equal to

y-y1=m(x-x1)

use the point B (7,7)

y-7=(-7/6)*(x-7)

therefore

the answer part c) is

y-7=(-7/6)*(x-7)

Part d)

we know that

the equation of the line in slope-intercept for is equal to

y=mx+b

we have

y-7=(-7/6)*(x-7)

y=(-7/6)x+(49/6)+7

y=(-7/6)x+(91/6)

therefore

the answer Part d) is

y=(-7/6)x+(91/6) or y=-1.167x+15.167
