200 POINTS FOR ANSWERING CORRECTLY!

Answer:
f(x) = x - 2
Step-by-step explanation:
so to make the equation you have to use the formula y2 - y1/ x2 - x1 to find the slope sooo
lets use the points (3, 1 ) and (4, 2)
2 - 1/ 4 - 3
1/1
1
so rn the equation looks like:
y = x + b
now to find b we have to substitute a point we did not use yet sooo
(5,3)
3 = 5 + b
b = -2
y = x - 2
now to check we substitute the last point
4 = 6 - 2?
4 = 4
Take two points
Slope:-
[tex]\\ \sf\longmapsto \dfrac{1}{1}=1=m[/tex]
Equation in point slope form
[tex]\\ \sf\longmapsto y-1=1(x-3)[/tex]
[tex]\\ \sf\longmapsto y-1=x-3[/tex]
[tex]\\ \sf\longmapsto y=x-2[/tex]
