form is y=mx+b
we just need to determine slope m and intercept b
you are given
x=-1
y=2
m=3
so
2= 3*(-1)+b
or b=5
then put m and b in form permanently and you can use it to solve for any other point on htat line:
y=3x+5

2 = 3(-1) + b
2 = - 3 + b
2 + 3 = b
b = 5
the equation of the line is y = 3x + 5 answer//
