  • See Below.

coordinates: (6,10), (11,15)

slope:


\sf \boxed{(y2-y1)/(x2-x1) }

using the formula:


(15-10)/(11-6)


(5)/(5)


1

equation:

y - y1 = m ( x - x1 )

y - 10 = 1(x-6)

y = x -6 + 10

y = x + 4

Sentence:

y is increasing by 1 with every increase in x by 1

Answer:


b=a+4

Explanation:

First calculate the slope by using the slope formula:


m=(y_2-y_1)/(x_2-x_1)

where m is the slope and
(x_1,y_1) and
(x_2,y_2) are two ordered pairs of the set.

Then use the point-slope form of the linear equation:


y-y_1=m(x-x_1)

Question d


(a_1,b_1)=(6,10)


(a_2,b_2)=(11,15)


\implies m=(b_2-b_1)/(a_2-a_1)=(15-10)/(11-6)=1


\implies b-10=1(a-6)


\implies b=a+4
