Write the equation of the line that passes through the points (-2,-8) and (8,−8).

Answer 1

y coordinates are the same: -8

so the equation of the line is y=-8

or if you really want, use the slope form "rise over run" (-8- -8)/(8--2) = 0/10 = 0

plug that into your slope intercept form of a linear equation

y = mx + b, with m= 0

that leaves

y = (0)x + b = b . Solve for b by plugging in either point such as (-2,-8)

-8 =(0)(-2) + b

b = -8

the equation is y = -8
