Write an equation in slope-intercept form of the line that passes through (3,8) and (1,-2)

Answers

Answer 1

Step-by-step explanation:

let eqn be y = mx + b.

m = (-2 - 8)/(1 - 3) = 5

sub (3, 8):

8 = 5(3) + b

b = -7

therefore equation of the line is y = 5x - 7

Answers

Step-by-step explanation:

y=mx+b

200 = 8x + 40

Rearrange,

x = 160/8 = 20

He would need to save $20 a week

200= 20 × 8 + 40

Answer:

8x + 40 ≥ 200At least $20 each week

Step-by-step explanation:

Target amount = at least $200Jason already has = $40Time = 8 weeksSaved amount each week = x

Answer:

Step-by-step explanation:

multiply

8x - 12 = 28

add 12 to both sides

8x = 40

divide

5

Answer:

Start with what we know:

4(2x-3) = 28

Now we do rainbow property aka distributive property:

4*2x=8x

4*-3=-12

now we have:

8x - 12 = 28

we have to get 8x alone:

we will add 12 to both sides:

8x= 40

now we have to get x alone:

8x/8=x

40/8=5

now we put that into a equation:

x=5
