Answer:
The y intercept is - .6
Step-by-step explanation:
We can use the slope intercept form of a line
y = mx+b
where m is the slope and b is the y intercept
y = 1/4x +b
Substitute the point into the equation
-1/2 = 1/4 (.4) +b
-1/2 = .1 +b
Subtract .1 from each side
-.5 - .1 = .1 + b - .1
-.6 =b
The y intercept is - .6
