Which coordinate do the graphs of y equals 2x plus 8 and x plus y equals --1 intersect?

y=2x+8
x+y=-1
From the second you get x = -1-y, put in the first y=2*(-1-y)+8 then y = -2 y +6
3y = 6 => y = 2 and x = -3

Where do graphs 2x plus 3y equals 12 and 2x-y equals 4 intersect?
x = 3 and y = 2 (3,2)
What is the point of intersection of the lines 5x plus 7y plus 29 equals 0 and 11x -3y -65 equals 0 on the coordinate plane?
By a process of elimination and substitution the lines intersect at: (4, -7)
Are y equals -3x plus 2 and y plus 3x equals 4 parallel?
Their graphs are.
Do y equals x and y equals x plus 2 intersect?
No, equations with the same slope do not intersect unless they are the same line.
What do graphs of all equations in the form y equals mx plus b have in common?
They are all lines. Their equations are written in the slope-intercept form, where we clearly can see if they just intersect, or are perpendicular to each other, or parallel, or coincide.
What is the x-coordinate of the vertexy equals x2 - 8 plus 16?
4
What is the graph of 6x-6y equals -48 and -10x plus 4y equals 92?
Two straight lines that intersect.
Where do lines 6x-2y equals 4 and 2x plus y equals 8 intersect?
At the point (2, 4).
What is the x and y of x-y equals -1 and -x plus y equals -1?
-2
What is the point of intersection of the lines 5x plus 7y plus 29 equals 0 and 11x -3y -65 equals 0?
It works out that they intersect at: (4, -7)
What is the ordered pair of 4x-7y equals -23 8x plus 5y equals 49?
The lines intersect at (3, 5)
What are the coordinates for x2 plus y2 equals 185 and x plus y equals 17?
We believe that those equations have no real solutions, and that their graphs therefore have no points of intersection.
