distance formula
The distance formula is really just the Pythagorean Theorem in disguise. To calculate the distance AB between point A(x1,y1) and B(x2,y2) , first draw a right triangle which has the segment ¯AB as its hypotenuse. Since AC is a horizontal distance, it is just the difference between the x -coordinates: (x2−x1)
slope formula
To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). The equation used to calculate the slope from two points is: On a graph, this can be represented as: There are three steps in calculating the slope of a straight line when you are not given its equation.
midpoint formula
The midpoint is halfway between the two end points: Its x value is halfway between the two x values. Its y value is halfway between the two y values.

You would need 16 because 3 × 4 = 12 and you need to do the same to the blue so you would do the equation 4 × 4 = ? which is 16.
Firsly remove the $350
$625-$350=$275
Each person is $6,so divide that from $275
275/6=45R5
The remaining $5 cannot be used to pay for another person,so we leave it as extras.
Therfore,45 people were at the the party.
Its A 0.125 because 0.125×8=1.000 or 1 full
