hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (4, 3) and (x2, y2) = (8, 4).
Slope a is  .
Intercept is found from equation  , or  . From that,
intercept b is  , or  .
y=(0.25)x + (2)
Your graph:

so, your equation is:

There are more than one form in which the equation of a line can
be in. The other tutor found one form of the equation, but that
is probably not the one listed on your homework. So what that tutor
did is not going to help you. Since you did not list the equations,
we cannot tell. But here is what you are to do:
For each listed equation, substitute x=4 and y=3 into that equation
and simplify. If you get an identity, such as 3=3, then substitute
x=8 and y=4 into that same equation. If you get an identity BOTH
times, then that is an equation of a line that passes through BOTH
points. But if you get a contradiction either or both times, such as
2=3, then you can eliminate that answer.
