3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
Finding the slope using two points:
The formula for slope is
In this case you have the points (-3, 5) and (4, 5):
^^^Plug these numbers into the formula for slope...

0
^^^This is your slope
Hope this helped!

It should be just 12b, since they all have the same exponent, they can all be combined.
