Answer:

m= 0

b= -1

- In the equation: y=mx+b, m stands for the slope and b stands for the y coordinate where the line crosses the y axis. Looking at a graph, you can see that it has a zero slope and that the line crosses -1 at the y intercept.

What is the slope of a line parallel to the line whose equation is

Lyrx [107]

Answer:

slope = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

9x - 3y = - 54 ( subtract 9x from both sides )

- 3y = - 9x - 54 ( divide all terms by 0 3 )

y = 3x + 18 ← in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

slope of parallel line is 3

Please help soon! Thanks! Solve for x

spin [16.1K]

Answer:

$x=27\degree$

Step-by-step explanation:

$\because AC || DE.... (given)$

$\therefore m\angle CAD= m\angle EDF\\ (corresponding \: \angle s)$

$\therefore m\angle BAD= m\angle EDF\\(\because B\in \overleftrightarrow{AC})$

$\therefore m\angle BAD= 2x\\(\because m\angle EDF=2x)$

$In\:\triangle BAD,$

$m\angle BAD+m\angle BDA+m\angle ABD= 180\degree$

$2x+2x+72\degree = 180\degree$

$4x= 180\degree -72\degree$

$4x= 108\degree$

$x= \frac {108\degree}{4}$

$x=27\degree$

Find the value of x that will make A||B

Jlenok [28]

Answer:

x=20

Step-by-step explanation:

For A to be parallel to B, the angles of 5x+20 and 3x+60 must be equal.

5x+20=3x+60

2x=40

x=20

I need help with this question!!!

CaHeK987 [17]

K is equal to 2.

You have to move the 4 to the other side and change the addition sign to subtraction. After that, you have to subtract 8 and 4 which will give you 4 and 4 divided by 2 is 2 which means that k equals 2.
