Answer:
y=1/2x+2
Explanation:
given the 2 equations, you know the following:
when x=2, you get a value of 3, let's call it Y
same with the next equation: when x=6, Y = 5
so the slope will be the diff b/w ys and then divided by diff of x's
so 5-3=2 is the diff of y
6-2=4 is the diff of x
divide 2/4 = 1/2 so the slope is 1/2
then you know the equation would be something like y=1/2 x but then you need to decide the intercept
1/2 of x when x=6 is 3, but Y =5
so you know the intercept is 2..
so the linear f(x) would be y=1/2x+2
done
