Question

Write an equation for the horizontal line that passes through (10,7). Give an answer in slope intercept form (if possible)

Answer 1

a straight line in general form is:

y = mx +b

where m is the slope = 0 for a horizontal line,  and b is the intercept

thus

y = b = 7

Answer 2

Slope-intercept form of the equation of a line is:

   y = mx + b       where m=slope and b is the y-intercept

 

Any horizontal line has a slope m=0     [remember rise (none) over run]

 

Also, the y value is always 7, as it is at point (10,7) and at the y-intercept (so, b=7).

 

In slope-intercept form, the line is:

   y = 7
