how do I write an equation in slope-intercept form of the line that passes through the points (-3,-4) and (3,0)

1 answer:

5 0

First find slope
(0+4)/(3+3) = 4/6 = 2/3
Y = 2/3x + b
Plug in any point
-4 = 2/3(-3) + b
-4 = -2 + b, b = -2
Solution: y = 2/3x - 2

What is the answer to 1/8(8x+15)=24

Korvikt [17]

Answer:

x = 177/8

Step-by-step explanation:

First, we must get rid of the fraction by multiplying 8 by both sides.

8 · 1/8(8x + 15) = 24 · 8

1(8x + 15) = 192

8x + 15 = 192

Then we simplify. First subtract 15 from both sides.

8x + 15 - 15 = 192 - 15

8x = 177

Then divide 8 from both sides.

8x/8 = 177/8

x = 177/8

Find the constant of variation k for the direct variation x -1 0 2 5 f(x) 2 0 -4 -10

Fofino [41]

Answer:

k = -2

Step-by-step explanation:

x -1 0 2 5

f(x) 2 0 -4 -10

ƒ(x) = kx

Substitute a pair of values for x and ƒ(x)

-10 = k×5

Divide each side by 5

k = -2

The constant of variation k = -2.
