Answer:

slope: - \frac{2}{9}    y intercept: 2

Step-by-step explanation:

you need to rearrange the equation into a y=mx+b formation

m is always the slope b is always the y intercept

the new equation of would be

y=-\frac{2}{9} x+2

I hope this helps somewhat!:)

PLEASE HELP I DO NOT UNDERSTAND AT ALL AND SHOW YOUR WORK !!
Agata [3.3K]

Answer:

y intercept (-6,0), x-intercept (0,-8) : y = \frac{-4}{3}x -8

y intercept (0,-6), x-intercept (-2,0): y = -3x -6

y intercept (0,8), x-intercept (1.6,0): y = -5x + 8

y intercept (0,7), x-intercept (-1.4,0): y = 5x + 7

Step-by-step explanation:

y = mx + b

*note: b is the y intercept

<u>1. y intercept (-6,0), x-intercept (0,-8)</u>

m = \frac{-8 - 0}{0 - (-6)}= \frac{-8}{6}  = \frac{-4}{3}\\y =  \frac{-4}{3}x + b\\y = \frac{-4}{3}x -8

<u>2.y intercept (0,-6), x-intercept (-2,0)</u>

<u />m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2}  = -3\\y = -3x + b \\y = -3x -6<u />

<u>3. y intercept (0,8), x-intercept (1.6,0)</u>

<u />m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8<u />

<u>4. y intercept (0,7), x-intercept (-1.4,0)</u>

<u />m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7<u />

Two numbers total 63 and have a difference of 31. Find the two numbers
Anastaziya [24]

Answer: 47 and 16

Step-by-step explanation:

- Make Two Equations

x + y = 63

x - y = 31

- Set one of the equations equal to one of the variables

x + y = 63

x = 31 + y

- Substitute the equation back into the other one

(31 + y) + y = 63

31 + 2y = 63

2y = 32

y = 16

- Substitute the answer back into the equation

x + y = 63

x + 16 = 63

x = 47
