SLOPE return to index

The slope of an equation is the coefficient of
x when the coefficient of y is one. **
In this problem 4y = 7x + 2 Seven is not the slope because the y
coefficient is 4 Solve for y; y = 7/4 x + 2/4
The slope is 7/4 **

**What is the slope of 3y = 6x + 9?
answer**

**The slope of parallel lines are
equal! Are the following lines parallel?**

**y = 3.5x + 6 and y = 3.5x - 6
answer**

**When multiplied together the
slope of perpendicular lines are equal to negative one.
Are the following lines perpendicular?
**

** y = 3x + 7 and y = - 1/3 x + 2
** answer

The graph of y = 3 is a horizontal line and the graph of x = 2 is a vertical line.

Horizontal and vertical lines are perpendicular to each other by the definition of vertical and horizontal lines
