Answer:
y=2
Explanation:
Hello
we can use two points and find the equation of the line
let
P1(1,5) P2(-1,-1)
the slope is

Now, with P1 and the slope-point equation find f(x)

the line interceptes y-axis when x=0,the value of y-intercept is
y=3(0)+2
y=0+2
y=2, intercept
I hope it helps
have a fantastic day
