Answer:
f(x) = x - 2
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
