First, every time when you ask question like this about function you must give elements of the initial set.

Definition of the function is - Every element of the starting set (domain- x)

must be related to only one element of the second set ( codomain-range-y).

In your case you have element (coordinate) x=3 which is in the relation with two elements (coordinates) y=2 and y=5 and that is relation but not function.

Good luck!!!

The answer to your question is,

No. It is not a function. Reasoning behind this is because there are repeating numerators. You can NOT have two of the same numerator as that will not form correctly if graphed. Two threes.

Which equation represents a line that passes through (-2, 4) and has a slope of 1/2?

jok3333 [9.3K]

Answer:

$\large\boxed{y-4=\dfrac{1}{2}(x+2)\text{- point-slope form}}\\\boxed{y=\dfrac{1}{2}x+5\text{- slope-intercept form}}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We have the slope $m=\dfrac{1}{2}$ and the point $(-2, 4)$ .

Substitute:

$y-4=\dfrac{1}{2}(x-(-2))$

$y-4=\dfrac{1}{2}(x+2)$ - point-slope form

Convert to the slope-intercept form (y = mx + b):

$y-4=\dfrac{1}{2}(x+2)$ <em> use the distributive property</em>

$y-4=\dfrac{1}{2}x+1$ <em>add 4 to both sides</em>

$y=\dfrac{1}{2}x+5$ - slope-intercept form

PLS help<br> solve for x: -6(2x-5) = 18

Mashutka [201]

Hey!

$-6(2x-5) = 18$

Switch it around and it becomes:

$2x - 5 = 18 \div -6$

First find 18 ÷ -6

$18 \div -6 = -3$

Positive ÷ negative OR negative ÷ positive is always negative.

That leaves you with:

$2x - 5 = -3$

Switch that around and it becomes:

$-3 + 5 = 2x$

Find -3 + 5

$-3 + 5 = 2$

That leaves you with:

$2 = 2x$

Divide both sides by 2 to leave <em>x</em> alone

$\frac{2}{2} = \frac{2x}{2}$

$\framebox{x = 1}$

What is the slope of a line perpendicular to the line whose equations is x-y=6

belka [17]

Answer:

m = -1

Step-by-step explanation:

First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept

x-y = 6

subtract x from each side

-y = -x+6

Multiply each side by -1

y = x-6

The slope is 1

Perpendicular lines have slopes that multiply to -1

m * 1 = -1

m = -1

The slope of the perpendicular line is -1

1.what is the slope of the line passing through the points (1,-5) and (4,1)?

hoa [83]

Answer:

C. 2

Step-by-step explanation:

Slope = (y2-y1) / (x2-x1) , (x1,y1) = (1,-5) , (x2,y2)=(4,1)

= (1-(-5)) / (4-1)

= (1+5) / 3

= 6/3

= 2
