What does it mean for two lines to be parallel?
Parallel lines are two or more lines that are the same distance apart, never merging and never diverging. The English word "parallel" is a gift to geometricians, because it has two parallel lines in it, in the form of the two side-by-side ls. It reminds you of what it means!

How to find the crossing point of two unknowns?
When we solve for two unknowns in two equations, we are finding the point where two lines cross. To find the crossing point ( x2, y2) we substitute y = (-3/4) x into y = (4/3) x + 5 and solve for x. You can label your solution as x2 at the end or at the beginning. Labeling x as x2 and y as y2:
What is the slope of a perp line?
The simplest is the perp line passing through origin. This line has the form y = (-3/4) x. Note the slope is the negative reciprocal of 4/3. All perp lines have a negative reciprocal, sometimes called opposite reciprocal, slope to the line they are perpendicular to. We are choosing the perp line through the origin because it has an intercept of zero. Let's plot the perp line along with the two parallel lines:
What is a perpendicular street?
With parallel streets, like Elm Street and Oak Street, a perpendicular street lets us cross over from one parallel street to the other. Streets have a finite length, so there's a finite number of perpendicular streets between any two parallel streets. Lines, however, are infinitely long, so there's an infinite number of perpendicular lines, or perp lines, crossing line 1 and line 2. Since we have to choose one perp line, we might as well choose one that simplifies the calculations.
What happens if two lines are parallel?
If two lines are parallel, then they will have same slope. The equations of parallel lines will differ only by the constant.
Do parallel lines differ by constant?

How to find the distance between two lines?
Steps to Calculate The Distance Between Two Lines 1 Check whether the given equations of parallel lines are in slope-intercept form (i.e. y= mx + c) or not. 2 Also, if the equations of lines are given in the slope-intercept form the slope value should be common for both lines. 3 Now find the value of interception point (c 1 and c 2) and find the value of slope for both the lines. 4 Substitute the values in the slope-intercept equation to calculate the value of y. 5 In the last, Put all the values in the distance formula discussed below to find the distance between two lines.
How to tell if two lines are parallel?
To know whether the two lines are parallel or not, we can check the slope of the two lines. If the slope of the two lines is equal then the two lines are parallel. To find out the slope, we convert the given equation of the line into slope-intercept form and compare the two equations to find the value of the slope of the lines.

What happens to the slope of two parallel lines?
If the two lines are parallel, the distance between the two lines will never change. For two parallel lines, the slope of both the lines will be the same but the y-intercept of each line will vary. The shortest distance between the two lines can be calculated if we have the equation of the two lines.
What is parallel line?
Parallel lines are the lines with the same slope. The distance between the two lines will never change. Some examples of the parallel lines are: 5x + 3y + 6 = 0 and 5x + 3y – 6 = 0 are parallel lines, and y = 5x + 5, and y = 5x - 7 are the parallel lines. We can confirm that the slope of parallel lines given here is the same. i.e., m1 = m2 = 5.
Do parallel lines have solutions?
As the property of parallel lines is that they never intersect each other, other than at infinity, they can not have any solutions. Solutions of parallel lines do not exist, hence it is known that the parallel lines have no solution. And the equations of the parallel lines are known as the inconsistent set of equations.
