What is the point of contact when the lines of 5x plus 7y plus 29 equals 0 and 11x -3y -65 equals 0 intersect each other showing work?

If: 5x+7y+29 = 0 and 11x-3y-65 = 0
Then: 5x+7y = -29 and 11x-3y = 65
Multiply all terms in the 1st equation by 11 and all terms in the 2nd equation by 5
So: 55x+77y = -319 and 55x-15y = 325
Subtract the 1st equation from the 2nd equation: 92y = -644 => y = -7
Therefore by substitution the point of contact is at: (4, -7)

When 2 straight lines intersect the sum of the adjacent angles equals?
180 degrees
Where do lines 6x-2y equals 4 and 2x plus y equals 8 intersect?
At the point (2, 4).
What is the term for lines that don't intersect?
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Do parallel intersect?
no they are straight lines that never intersect, intersecting lines intersect.
Do skew lines always intersect?
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
What shape has lines that never intersect?
A common shape that has lines that never intersect is the equals sign. Shapes that include intersecting lines but also have others that will never intersect include squares, rectangles, and rhombuses.
When 2 straight lines intersect the sum of the adjacent angles equals?
180 degrees
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?

What is parallel planes?
Lines in the same plane that do not intersect Lines in the same plane that do not intersect Lines in the same plane that do not intersect Lines in the same plane that do not intersect
What is the term for lines that don't intersect?
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Do parallel intersect?
no they are straight lines that never intersect, intersecting lines intersect.
Do skew lines always intersect?
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
Do lines that skew intersect?
No. Skew lines do not intersect
Which phrase describes perpendicular lines the lines never touch or the lines intersect at a right angle or the lines intersect at an acute angle or the lines intersect at a obtuse angle?
Lines that intersect at right angles.
How do you solve the system by graphing -5x-y equals -2 x-3y equals 10?
Where the lines intersect that gives the values for x and y in the two equations. The lines should intersect at (1, -3) because x = 1 and y = -3
What is the ordered pair of 4x-7y equals -23 8x plus 5y equals 49?
The lines intersect at (3, 5)
