I'll assume over means or.
To find the equation of this line, we first need to find the slope. The slope is the change in y over the change in x. Here, we can find the slope by doing (9-7)/(6-3), which gives us 2/3 as our slope.
The next step is to substitute the values of x and y in our equation that we have made so far, y=2/3x+b. Substituting values of x and y from point (3,7), we get 7=2+b, giving us a b value of 5. So, whichever equation simplifies to y=2/3x + 5 will be our equation.
