Question

Write an equation of the line that passes through (8, 3) and (4, 3).
A. y = 3
B. y = 4x + 3
C. y = 4
D. y = 3x

Answer 1

Substituting third equation into second equation,
3= 4m + (3-8m)
3= 4m +3 - 8m
-4m= 0
m = 0

When m =0, from first equation,

3 = 8m +c
3= 8(0) + c
c = 3


Therefore, y = mx +c
y = (0)x + 3
y = 3 (Equation) so it was A

Hope this Helps!
