2.2.AP-10 Question Help
Explain why it does not matter which point you choose when writing the equation of the line in point-slope form, given two points.
Choose the best answer below.
O A. Point-slope form subtracts the Xy- and y, -values. Therefore, the slope of the line will always be positive, as a negative
number divided by a negative number is always positive.
B. A line that goes through both points has a constant slope, so choosing either point will result in an equivalent equation.
OC. The point-slope form is based on two known points, so it will always produce the equation for a line, though different points
will produce the equations for different lines.
OD. Points on a line are always listed from left to right, so choosing the first point on the left will always ensure the same point
is chosen for the second point.
