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

PSYCHO15rus [73]

Answer:

m = $\frac{f+1}{7}$

Step-by-step explanation:

f = 4m + 3m -1

f = 7m - 1

Adding 1 to both sides

f+1 = 7m

Dividing both sides by 7

m = $\frac{f+1}{7}$
