Answer:

B) 0

Step-by-step explanation:

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

m=(-2-(-2))/(9-3)

m=(-2+2)/6

m=0/6

m=0

The answer is B. 0
when it’s a straight horizontal line, the slope is always going to be zero. It’s only going to undefined if the line is vertical.

Answer:

Solving the given linear system, we get x = 1 and y = -3.

The solution set is: (1,-3)

Step-by-step explanation:

We need to solve the linear system of equations.

$3x-y=6 \\y=x-4$

We can write second equation y=x-4 as: $-x+y=-4$

Let:

$3x-y=6--eq(1)\\ -x+y=-4--eq(2)$

Now, Adding equation 1 and 2

$3x-y=6\\ -x+y=-4\\--------\\2x+0y=2\\2x=2\\x=\frac{2}{2}\\x=1$

So, we get x = 1

Now, put value of x in second equation to find value of y:

$y=x-4\\Put\:x=1\\y=1-4\\y=-3$

So, we get y = -3

Solving the given linear system, we get x = 1 and y = -3.

The solution set is: (1,-3)

Solve for z:<br> −0.25z=−1.25<br><br> z=?

lakkis [162]

$- 0.25z = - 1.25 \\ \Leftrightarrow \: z = \frac{ - 1.25}{ - 0.25} = \frac{ - \frac{5}{4} }{ - \frac{1}{4} } = 5$
