What is the equation of the straight line passing through the points (2, −1) and (−3, 4)?

Question

Accepted Answer

x + y = 1. Slope = (4 − (−1))/(−3 − 2) = 5/(−5) = −1. Using the point (2, −1): y + 1 = −1(x − 2), so y = −x + 1, that is x + y = 1. Both points satisfy it: 2 + (−1) = 1 and (−3) + 4 = 1.
