Question

So if slope is 2/3 but it goes thew (4,2) then what is b (y=2/3x____) (need b please help me out)

Answer 1

This is currently your equation since you do not know "b"

y = 2/3x + b

To find "b" you plug in the point (4,2) into the equation.

y = 2/3x + b

2 = 2/3(4) + b

2 = 8/3 + b (subtract 8/3 on both sides to get "b" by itself)

2 - 8/3 = b (make the denominators the same)

6/3 - 8/3 = b

-2/3 = b

So: y= 2/3x - 2/3
