How do I write this in slope intercept form: (-3,-4) and (4,-3)
DENIUS [597]
Slope intercept form is y = mx + b

Pick one of the coordinates, I’ll use (-3,-4) as the example.

Coordinates are just numbers plugged in for (x,y).

This means -3 would be your x and -4 would be your y.

So plug these numbers into the equation and you get -4 = m(-3) + b.

M is slope and to find slope, you need to do (y2-y1) / (x2-x1).

In other words, it would be (-3 - -4) / (4 - -3) = 1/7 which is your slope (m).

Now plug that in for m to get the b variable.

-4 = 1/7(-3) + b.

B = -3.57

Your answer is y = 1/7x -3.57

TV=3x-24 and VX=2x+1. What is the value of VX?<br> 1. 25<br> 2. 99<br> 3. 5<br> 4. 51
Maslowich
ΔTXV is an <span>isosceles triangle because ∡T = ∡X therefore TV = VX.

3x - 24 = 2x + 1    |subtract 2x from both sides

x - 24 = 1    |add 24 to both sides

x = 25

Factorise the following 4(x-1)²-9 need solution
kumpel [21]

Answer:x= 5/2 x= -1/2


Step-by-step explanation:

4(x-1)2-9

4(x2-2x+1) - 9

4x2 - 8x + 4 - 9

4x2 - 8x - 5

4x2 +2x - 10x - 5

2x(2x+1) - 5(2x+1)

(2x-5)(2x+1)

therefore, x= 5/2 x= -1/2
