Answer:

y=3/4x +3

Step-by-step explanation:

Find the slope first.   y-y over x-x

Y: 9-6 =3

X 8-4 = 4

so the slope is 3/4

Now choose one of the ordered pairs to use to substitute to find the y intercept or "b" in y=mx + b

I chose 4,6 since the slope has a 4 in the denominator

Use y=mx + b

Y =6 from ordered pair    m/slope= 3/4   x= 4 from ordered pair and you are looking for b

6= 3/4 (4) + b

6= 12/4 or 3 + b  subtract 3 from both sides

3= b

equation is y=3/4x +3

A tree is 7 ft tall when it is planted and this type of tree grows two feet per year. How tall will the tree be in 6 years? How
s344n2d4d5 [400]

2x+7=?

X=6

2(6)+7=

12+7=19

In six years, the tree will be 19ft

2x+7=44

Minus seven on both sides

2x=37

Divide two from both sides

X=18.5

Thus, it will take 18 and a half years for the tree to reach 44ft
