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 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 .
