Writing Linear Equations from Two Points

What are the two methods mentioned for finding a linear equation given two points?

• Slope-Intercept and Quadratic Formula

• Point-Slope and Slope-Intercept

• Quadratic Formula and Point-Slope

• Slope-Intercept and Exponential

What is the point-slope form of a linear equation?

• y = mx + b

• y = ax^2 + bx + c

• y - y1 = m(x - x1)

• ax + by = c

How do you label the points when given two points?

• a, b and c, d

• p, q and r, s

• m, n and o, p

• x1, y1 and x2, y2

What is the formula for calculating the slope (m) using two points?

• m = (y1 - y2) / (x1 - x2)

• m = (x1 - x2) / (y1 - y2)

• m = (y2 - y1) / (x2 - x1)

• m = (x2 - x1) / (y2 - y1)
