Answer:

A relation is a function if x values never repeat, so every input will only have one output. If the function is graphed you can do the vertical line test, a relation passes if you can draw a vertical line anywhere on the graph and it only intersects with the relation once.

Help me please show how you got the answer

Answer:

Firstly you need to put the equation in form of. y =ax+b

Let us do it

We have

2x-2y=18

-2y=18-2x

-y=(18) /2 - (2x)/2

-y =9-x

Mutiply by - to remove it beside y

Y=-9+x

Which is y=x-9

Slope =a=1

Yintercept=b=-9

The graph of 4x+12y=8 and y=Mx+5 are perpendicular. What is the value of m

Komok [63]

Answer:

$m=3$

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

step 1

Find the slope of the given line

we have

$4x+12y=8$

isolate the variable y

$12y=8-4x$

$y=\frac{2}{3}-\frac{1}{3}x$

the slope of the given line is

$m=-\frac{1}{3}$

step 2

Find the slope $m_2$ of the perpendicular line to the given line

$m_1*m_2=-1$

$m_1=-\frac{1}{3}$ ---> slope of the given line

$(-\frac{1}{3})*m_2=-1$

$m_2=3$

therefore

The value of m is

$m=3$
