Answer:

y = - 4x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ )= (1, - 2) and (x₂, y₂ ) = (2, - 6) ← 2 ordered pairs from the table

m = $\frac{-6+2}{2-1}$ = $\frac{-4}{1}$ = - 4, thus

y = - 4x + c ← is the partial equation

To find c use any ordered pair from the table

Using (1, - 2), then

- 2 = - 4 + c ⇒ c = - 2 + 4 = 2

y = - 4x + 2 ← equation in slope- intercept form

There are 4 balls in a bag, each of a different color. 4 balls are picked out of the bag randomly, one at a time, and after the

blsea [12.9K]

Answer:

$\frac{1}{256}$

Step-by-step explanation:

Your total is 4 and each one is a individual (1)

so the probability of 1 ball would be :

$\frac{1}{4}$

because the question asks for the probability they are picked 4 times, we would need to multiply ¼ four times.

$\frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{256}$

Find the slope of the line through points (5,2) and (-6,3).

fenix001 [56]

Answer:

-1/11

Step-by-step explanation:

The slope of a line when given two points is found by

m = (y2-y1)/(x2-x1)

= (3-2)/(-6-5)

=1/-11

= -1/11

PLEASE help.

1 - Not Rent
2 - Not rent
3 - Rent
4 - Rent
5 - I think Not rent?
6- not rent.

5 Can be fixable, because you can just simply not do any of those things. But if that’s not an option I would definitely say not rent
