User: Input in standard form the equation of the given line. The line through (0, -3) and (3, 0)

User: The y-intercept of the line whose equation is 3x - 2y = 6 is -3 2 6

Weegy: The y-intercept of the line whose equation is 3x + 2y = 7 is 7/2.



User: The x-intercept of the line whose equation is x - y = 3 is -3 0 3

Weegy: The y-intercept of the line whose equation is y = x - 3 is -3.



User: The slope of the line whose equation is 2x + 5y + 1 = 0 is -2/5 -1/5 5/2

User: x + y = 6 2x - y = 3 The system of equations has no solution has one solution is coincident

Weegy: 8x^2 - 2x = 1;
8x^2 - 2x - 1= 0;
(4x + 1)(2x - 1) = 0
(4x + 1) = 0; 4x = -1, x = -1/4 or (2x - 1) = 0; 2x = 1; x = 1/2

Solution set: {x = -1/4, x = 1/2}

Input in standard form the equation of the given line. The line through (0, -3) and (3, 0) is x - y - 3= 0.
Slope = (0 + 3)/(3 - 0) = 3/3 = 1
y + 3 = 1*x
x - y - 3 = 0

The y-intercept of the line whose equation is 3x - 2y = 6 is -3 .
3x - 2y = 6
2y = 3x - 6
y = 3/2x - 3
-3 is the y-intercept .

The x-intercept of the line whose equation is x - y = 3 is 3.
x - y = 3
when y = 0
x - 0 = 3
x = 3 .

The solution for x + y = 6 , 2x - y = 3 is x = 3 , y = 3 ,it has one solution .
Equation 1 add equation 2 ,
x + y + 2x - y = 6 + 3
3x = 9
x = 9/3
x = 3
3 + y = 6
y = 6 - 3
y = 3 .

11x = 19 is not a result of solving the system of equations by addition for 5x + 2y = 5 , 3x - y = 14 .
3x*2 - 2*y = 14*2
6x - 2y = 28
5x + 2y + 6x - 2y = 28 + 5
11x = 33 .

There no solution for x - y = 6 , x = y + 2 Solve the system of equations by substitution.
Put equaiton 2 in euqation 1 , we get the result as follows:
x - y = 6 ,
y + 2 - y = 6 ,
2 = 6 ,
2 is can't be equal to 6 ,
So it has no solution .

The solution for 8y - 1 = x , 3x = 2y is (1/11, 3/22) .Solve the system of equations by substitution.
put equation 1 of x = 8y - 1 in equation 2 ;
3(8y - 1) = 2y ;
24y - 3 = 2y ;
22y = 3 ;
y = 3/22 ;
x = 8*3/22 - 1 ;
x = 24/22 - 22/22 ;

The equations 2x - y = c , x + 2y = d are intersecting .
The slope of 2x - y = c is 2 , the slope of x + 2y = d is -1/2 , so 2 lines are perpendicular to each other ,so they are intersecting .
