What is the reflection image?

Which of the following lines is not parallel to the graph of y=4x+7. y-4x=9 4x-y=8 . 4y-x=8 8x-2y=8

DENIUS [597]

y = 4x + 7

This equation is in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. The slope of this line is 4. Parallel lines have the same slope, thus a line not parallel to this line will not have a slope of 4. Let's check which of these lines does not have a slope of 4.

y - 4x = 9

y = 9 + 4x (add 4x to both sides)

y = 4x + 9 (switch the constant and x-term)

This line has a slope of 4.

4x - y = 8

-y = 8 - 4x (subtract 4x from both sides)

y = -8 + 4x (divide both sides by -1)

y = 4x - 8 (switch the constant and x-term)

This line has a slope of 4.

4y - x = 8

4y = 8 + x (add x to both sides)

y = 8/4 + x/4 (divide both sides by 4)

y = x/4 + 2 (simplify and switch constant and x-term)

This line has a slope of 1/4. It is thus not parallel to the line y = 4x + 7.

Answer:

4y - x = 8

What is the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3

andreyandreev [35.5K]

Answer:

The equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 is $y+6=\frac{1}{3}(x+2)$

Solution:

Given that line passes through (-2, -6) and has slope of 1/3

We have to find the equation of the line

The point slope form is given as

$y-b=m(x-a)$

where m is the slope of the line and a, b are the x, y coordinates of the given point through which the line passes.

Here in this question, m = 1/3 and a = -2 and b = -6

By substituting in point slope form we get,

$y - (-6) = \frac{1}{3}(x - (-2))\\\\y + 6 = \frac{1}{3}(x + 2)$

Hence the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 is $y+6=\frac{1}{3}(x+2)$

“Genetic power is far more potent than atomic power. And it will be in everyone's hands. It will be in kits for backyard gardene

steposvetlana [31]

Even though this is not maths, let me help you. In order to answer the first question I suggest you to try to imagine what would happen if people had the power to genetically alter things. It might be helpful to think about how it would affect your life. In that case you would come up to the answer on what should I do with my genetic power.
Now for the second one, let me say that science cannot answer because results are not in the hands of the scientists, but in the hands of the people.
I hope this info can help

15+9=?(5+3) please help

Tema [17]

Answer:

3

because 15 + 9 = 24

and 3(5 + 3) which is 3 * 5 + 3 * 3 = 15 + 9 = 24

= 24 = 24

It says write an equation of the line shown and the line goes through points 4,3 and 1,-3

RUDIKE [14]

Slope of the line;
slope= $\frac{change in y}{change in x}$
Slope= $\frac{3--3}{4-1}$
Slope,m = $\frac{6}{3} =2$
y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
