Question

What's the equation of the line slope 1/4 y-intercept: 3

Answer 1

In y = mx + b form, the m is ur slope and the b is ur y int.

y = mx + b
y = 1/4x + 3 <=== slope intercept form

or...
y = 1/4x + 3
-1/4x + y = 3
x - 4y = -12 <=== standard form

Answer 2

The general equation is y = mx + c .
All you have to do is to insert/subs it with the given value.
