The answer would be y=-x-4

3-(-2)/-1-4 is the slope
Simplified, the slope is -1
So far, we have y=-1x+b.
We know that 4,-2 is a point on this line, so we plug it in.
-2=-1(-2)+b which is the same as -2=2+b
Therefore b=-4
Then plug b back in. We get
y=-x-4 which is the answer

Answer:

<h3>The slope is -1.</h3>

Step-by-step explanation:

To find an equation of the line that passes through the points, you have to use the slope formula.

Slope:

\Rightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }

y2=3

y1=(-2)

x2=(-1)

x1=4

Solve.

3--2/-1-4=5/-5=-1

The slope is -1.

Suppose you just received a shipment of ten televisions. two of the televisions are defective. if two televisions are randomly​
amid [387]

Try this solution:

1. for probability of both televisions work:

P_{2w}=\frac{C^2_8}{C^2_{10}}=\frac{7*8}{9*10}=0.6(2)

2. for probability of at least on is defective (it means, the sum = one is defective and two are defective):

P_{1d}=\frac{C^1_2C^1_8}{C^2_{10}}=\frac{4*8}{9*10}=0.3(5) - for P(1defective);

P_{2d}=\frac{C^2_2}{C^2_{10}}=\frac{2}{9*10}=0.0(2) - for P(2defective);

totaly for at least one is defective:

P_{at \ least \ 1 \ d}=P_{1d}+P_{2d}=\frac{16}{45} +\frac{1}{45} =0.3(7)
