How do i solve y+4=4/3(x+1)

ICE Princess25 [194]

Y + 4 = 4/3(x + 1)...first we distribute
y + 4 = 4/3x + 4/3 ...now we subtract 4 from both sides
y = 4/3x + 4/3 - 4
y = 4/3x + 4/3 - 12/3
y = 4/3x - 8/3 <======
u will have a slope of 4/3....and a y int of (0,-8/3)...ur x int is (2,0)

in standard form, it is :
y = 4/3x - 8/3
-4/3x + y = -8/3
4x - 3y = 8....in case u need to find some points to graph

2x + 3y = -6<br> -2x + 3y = 6<br><br> How do I graph it

Elanso [62]

Answer:

$(-3, 0)$

Step-by-step explanation:

$\: \: \: 2x + 3y = - 6 \\ -2x + 3y = \: \: \: 6 \\ \frac{ + \: \: \: \: \: \: - \: \: \: \: \: \: = - }{ }{} \\ \: \: \: 4x \: \: \: \: \: \: \: \: \: \: \: \: = - 12 \\ \\ x = \frac{ - 12}{4} \\ \\ x = - 3$

now,

$-2( - 3) + 3y = 6 \\ 6 + 3y = 6 \\ 3y = 6 - 6 \\ 3y = 0 \\ y = \frac{0}{ 3} \\ y = 0$

thus, (-3, 0)
