Question

Write an equation of the line that passes through (8, 3) and (4, 3).

Answer 1

m=(3-3)/(4-8)


m=(0)/(4-8)


m=(0)/(-4)


m=0

--------------------------------------------------------------------------

y-y1 = m(x-x1)


y-3=0(x-8)


y-3=0x+0(-8)


y-3=0x+0


y-3=0


y=0+3


y = 3



So the equation of the line is y = 3

Answer 2

A quick way to get the answer is to notice that the y coordinates are equal to 3. So the equation is y = 3
