Answer:
Step-by-step explanation:
This is a linear function (a line), meaning it can be modeled in the form y=mx+b.
Taking two points that lie on the line, say (-1, 2) and (3, -1),
m=(-1-2)/(3-(-1))=-3/4.
So we have y=(-3/4)x+b.
Substituting in the point (-1, 2), we get that 2=(-3/4)(-1)+b
2 = 3/4 + b
b = 5/4
Therefore, y=(-3/4)x + 5/4.
