find standard form and slope intercept form

Question

slope=0 ; through (5,8)

Answer 1

In slope-intercept form:

 

y = mx + b             substitute (5, 8) and m = 0

8 = 0x + b

8 = b                      return to slope-intercept form

 

y = 8

 

A line with zero slope is a horizontal line passing through the "y" coordinate.
