Answer:
f(x)= -2/3x+2
Explanation:
first we find the slope using the slope formula y2-y1/x2-x1
4/3-2/3/1-2
2/3/-1
-2/3
-2/3 is the slope so we can write it into the equation
f(x)= -2/3x+b
y intercept or b is when x=0 and we see in the graph when x=0 then f(x)=2
so 2 is the y intercept and we can put it into the equation where b is
f(x)= -2/3x+2
hope this helps
