Algebra 2 URGENT PLEASE HELP

find an equation of the linear function f using the given information. please show all steps and work
f(1)=1, f(1)= 2

f(x1)=y1

f(1)=1
So x1=1 and y1=1
f(x2)=y2

f(1)=2
So x2=1 and y2=2
We have two points: (x1, y1) and (x2, y2) = (1, 1) and (1, 2).
The slope between those two points is (y2y1)/(x2x1) = (21)/(1(1)) = 3/2 = m
The equation for a line is (yy1) = m(xx1). Plug in y1, m, and x1 to get the answer.
[When you solve for y, you should get y=3/2x1/2]
