Answer:
y - 6 = 2/3( x + 1)
Step-by-step explanation:
Equation for point slope form
y - y1 = m( x - x1)
( x1 , y1) - point on the line
m - slope of the line
Given
Slope: 2/3
Point ( -1 , 6)
x1 = -1
y1 = 6
m = 2/3
Substitute the value into the equation
y - 6 = 2/3(x - (-1)
y - 6 = 2/3( x + 1)
The equation of the line in point slope form is
y - 6 = 2/3( x + 1)
Answer:
x=2.7142 y=-2.8571,
Step-by-step explanation:
given 4x-8y=12............(1)
14+2x=-6y
2x+6y=-14..........(2)
from equ (2) multiply by 2
4x+12y=-28............(3)
substruct (1) and (3)
4x-8y-4x-6y=12-(-28)
-14y=40 ,y==-2.8571
y=-2.8571 put in equ (1)
4x-8(-2.8571)=12
4x=12-22.857=10.8571
x=
x=2.7142
2a + 7b = 0 ⇒ 10a + 35b = 0
3a - 5b = 31 ⇒ 21a - 35b = 217
31a = 217
a = 7
2a + 7b = 0
2(7) + 7b = 0
14 + 7b = 0
7b = -14
b = -2
(x, y) = (7, -2)
