Ineed an answer asap! write the equation of the horizontal line passing through (7, 4).

So if it is going completely horizontally, you know that it will begin with the equation y=?. If you use the point (7, 4) then you know that y is 4. Therefore, the answer would be y=4.

There are ALOT of equations that can go through the point (7,4). So, pick a slope. it doesnt matter what it is. just pick a number. let us say you pick 3.

Your equation is now y=3x+b.

now you need to find b in respect to (7,4). plug 7 and 4 into the equation and solve for b.
now you have a function that runs through the coordinate (7,4)!

When Juan commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 31 minutes and a standard deviation of 4.5 minutes. Using the empirical rule, what percentage of his commutes will be between 22 and 40 minutes?
