Answers

Hello,
let's try by elimination

x+y=-1
y=x+3
We put the value of y into the first equation

x+(x+3)=-1
==>2x=-4
==>x=-2
So with the second equation, y= -2+3=1

What are the coordinates of the y-intercept of the line whose equation is LaTeX: 12x+13y=812 x + 13 y = 8? ( , )

Answers

The coordinates of the y-intercept of the line whose equation is

12 x + 13 y = 8 is 8/13.

As given in the question,

Given equation: 12x + 13 y=8

Convert the equation into y-intercept form

General form of y-intercept form is

y=mx + b

Subtract from the equation 12x from both the side of equation,

12x+13y-12x=-12x+8

⇒ 13y=-12x +8

Divide both the side by 13

13y/13= (-12/13)x +8/13

⇒y=(-12/13)x +8/13

To get y-intercept put x=0

y =8/13

Therefore, thecoordinates of the y-intercept of the line whose equation is 12 x + 13 y = 8 is 8/13.

The complete question is :

What are the coordinates of the y-intercept of the line whose equation is

12 x + 13 y = 8 ?
