Answer:

The correct answer would be C

Step-by-step explanation:

If you were to input the X and Y values of the two coordinates into equation C, you will see that the equation would be true for both coordinates, meaning that (4, -3) and (5, 0) are both points that are on the line Y + 3 = 3(X - 4).

Calculate the distance between the points H=(-2, -5) and K=(-7, 1) in the coordinate plane.

Rzqust [24]

Answer:

$d=\sqrt{61}$

Step-by-step explanation:

The distance is given by the expression $d=\sqrt{(\Delta x)^2+(\Delta y)^2}= \sqrt{[(-2)-(-7)]^2+[(-5)-(1)]^2} = \sqrt{(-2+7)^2+(-5-1)^2}=\sqrt{(5)^2+(-6)^2}=\sqrt{(25+36)}=\sqrt {61}$

Sketch a graph of −3x+y=2

DIA [1.3K]

You can do this by first finding the y intercept which is the point where x = 0

-3(0) + y = 2
so y intercept is the point (0,2)

Now find the x intercept by putting y = 0

-3x = 2

x = -2/3

So we have 2 points (-2/3, 0) and (0,2) Draw a line through these 2 points and you have the required graph.

Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a s

pantera1 [17]

Answer:

The slope of line k is - 4 .

Step-by-step explanation:

The slope of given line p is 1/4

Let the slope of line k which is perpendicular to is m.

When the two line are perpendicular to each other, the product of the slopes is always negative 1.

So, the slope of line k is given by

$m=- \frac{1}{\frac{1}{4}}\\\\m = - 4$

Do the law of order and the law of grouping apply to subtraction?

emmasim [6.3K]

Since we know that law of order states that sum or product of any two specific numbers will be same irrespective to their order. $a+b=b+a$ and $a*b=b*a$ .

Law of order is only applicable for addition and multiplication. It is not applicable to subtraction and division. Let us see it by an example.

$50-25\neq25-50$

$25\neq-25$

Law of grouping states that it does not matter how to order a group of numbers while adding or multiplying. $a+(b+c)=(a+b)+c$ and $a*(b*c)=(a*b)*c$ .

Law of grouping is not applicable to subtraction and division. Let us see it by an example.

$15-(5-3)\neq(15-5)-3$

$15-(2)\neq(10)-3$

$13\neq7$

Therefore, we can see that law of order and law of grouping is not applicable to subtraction.
