In the model equation, this is what the letters stand for— y=slope•variable+y-intercept. Since we already know the slope, let’s substitute this into the equation now.
y=3x+b
Now we need to find the y-intercept/b. We’ll do this by substituting the y and x value from the point into the equation and solving for b
y=3x+b
*substitute point*
11=3(3)+b
*multiply 3 and 3*
11=9+b
*subtract 9 on both sides
2=b
Now that we have b, let’s put this into the equation and finish the equation
y=3x+b

The best answer between the two choices would be the second option B) FALSE because the owner doesn't have to use his ''best'' judgement to figure out costs and expenses when it comes to sales.
