what does line 5 x + 2 y = 8

Question

 Is this a horizontal, vertical

Answer 1

Hi,

Always write your linear function in slope-intercept form to determine the type of line it represents.

 

5x + 2y =8

         y = -(5/2)x + 4        ...solve for y

 

The slope, m = -(5/2), therefore, the line is neither horizontal nor vertical. But, the line decreases as you go from left to right.

 

You should also remember, equations of 

1. horizontal lines are in y = c form
2. vertical lines are in x = c form.
