Write an equation for the line parallel to the given line that contains C

Mathematics
1 answer:
Ksenya-84 [330]3 years ago
7 0

Answer:

The equation would be y = -2x + 10

Step-by-step explanation:

To find the line parallel going through the given point, first note that parallel lines have the same slope. This means that we have a slope of -2 in the original line, therefore the parallel line will also have a slope of -2. Now we can use this and the given point to find the line using point-slope form.

y - y1 = m(x - x1)

y - 6 = -2(x - 2)

y - 6 = -2x + 4

y = -2x + 10

If 100% of a number is 15, what is 50% of the number?
anzhelika [568]

Answer:

Let n be the number

100% of a number is 15 is written as: 100% × n = 15

100% = 100 / 100 = 1

Hence

100% × n = n = 15

We now need to find 50% of the number

50% of 15 = (50 / 100) × 15 = 750 / 100 = 7.5

Step-by-step explanation:

Which equation of a line passes through the points (3, −1) and (6, 1)?
Vaselesa [24]

Answer:

Y = 2/3x - 3

Step-by-step explanation:

Recall the general equation for a straight line is

y = mx + b

where m is the gradient and b is the y-intercept

given 2 points whose coordinates are (x1, y1) and (x2, y2), m can be found with the following formula:

m = \frac{y1-y2}{x1-x2}

in this case, x1 = 3, y1 = -1, x2 = 6, y2=1

applying these values to the formula for m will give

m =  (-1 -1) / (3-6) = 2/3

We can see immediately that only the first (top-most) answer has this value for m and we can guess that this is probably the answer.

But we can still check to confirm:

If we substitute this back into the general equation, we get:

y = (2/3)x + b

In order to find the value for b, we substitute any one of the 2 given points back into this equation. Lets choose (6,1)

1 = (2/3)(6) + b

1 = 4 + b

b = -3

Confirm  Y = 2/3x - 3 is the answer.

hey! been a while since I've answered questions haha

typically I would put an explanation for my answers but this one's pretty straightforward so ¯\_(ツ)_/¯

a) mode is the number that occurs most often in a data set.

b) mean is the average or expected value in the data set

c) median is the value that lies in the midpoint in the data set.
