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

1. y intercept (-6,0), x-intercept (0,-8)

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

2.y intercept (0,-6), x-intercept (-2,0)

$m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2} = -3\\y = -3x + b \\y = -3x -6$

3. y intercept (0,8), x-intercept (1.6,0)

$m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8$

4. y intercept (0,7), x-intercept (-1.4,0)

$m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7$

Name the property of real numbers illustrated by the equation -3(x + 4) = -3x -12

vivado [14]

Answer:

Distributive Property

Step-by-step explanation:

They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.

-3 × x = -3x.

-3 × 4 = -12.

-3x - 12

F) Tyler’s gray paint is a darker shade of gray than Hillary’s gray paint

When we take Tyler’s amount, we should do 8/30, which equals approximately .27. When we do the same thing with Hillary’s amount (10/40), we get .25. .27>.25, meaning that for the amount of white paint there is, more black paint is going into Tyler’s. As we know, black makes paint dark, so Tyler’s would be darker.
