What's the difference between a parallel and perpendicular lines ?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Step-by-step explanation:

hope this helps

Parallel lines will continue beside one another forever without ever touching. Perpendicular lines meet at a 90 degree angle forming a T

Step-by-step explanation:

x-int: (3, 0)

y-int: (0, -3)

General Formulas and Concepts:

Alg 1

Slope-Intercept Form: y = mx + b

m - slope b - y-intercept

The y-intercept is the y value when x = 0.

Another way to reword that is when the graph crosses the y-axis.

The x-intercept is the x value when y = 0.

Another way to reword that is when the graph crosses the x-axis.

Step-by-step explanation:

Step 1: Define equation

x - y = 3

Step 2: Convert to slope-intercept form

Subtract x on both sides:                    -y = 3 - xDivide both sides by -1:                        y = x - 3

Step 3: Find x/y-intercepts

x-int

Set y = 0:                            0 = x - 3Add 3 to both sides:          3 = xRewrite:                              x = 3Write coordinates:             (3, 0)

y-int

Set x = 0:                            y = 0 - 3Subtract:                             y = -3Write coordinates:             (0, -3)
