Komok [63]2 years ago

Start off by writing the equation y = mx - b. Then plug in what you do know

3 = 2(-1) - b (m is the slope and parallel lines have the same slope). Then solve

3 = -2 - b

<u>+2  +2</u>

5 = b

So y = 2x + 5

For the equation 4(2x-4)=8x+k, what value of K will create an equation with infinitely many solutions? Please show steps
strojnjashka [21]
If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.

8x-16=8x+k

If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.

In which quadrant or on which axis do each of the points (-2,4) , (3,-1) ,(-1,0), (1,2) and
exis [7]

Answer:

Step-by-step explanation:

cartesian plane :

quadrant 1 : both x and y are positive

quadrant 2 : x is negative, y is positive

quadrant 3 : both x and y are negative

quadrant 4 : x is positive and y is negative

(-2,4)......we have x is negative and y is positive...so we are in quadrant 2

(3,-1)....we have x is positive and y is negative...in quadrant 4

(-1,0) ...if u have a 0 in ur points, they do not lie in any quadrant because they are located on an axis....this is located on axis x

(1,2)....both are positive....located in quadrant 1

(-3,-5)...both are negative.....quadrant 3
