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)

What is the slope (m) when the points are (-2, -6) and (4, 6)?

• 2

• 4

• 1

• 3

What is the next step after finding the slope (m) in the point-slope method?

• Find the x-intercept

• Find the y-intercept

• Find another point

• Find the midpoint

Which point is used to find the y-intercept in the example?

• (2, 3)

• (0, 0)

• (4, 6)

• (-2, -6)

What is the final linear equation derived in the example?

• y = -2x - 2

• y = 2x - 2

• y = -2x + 2

• y = 2x + 2

What is the common method to find the slope mentioned in the summary?

• Change of x over change of y

• Change of y over change of x

• Sum of x and y

• Difference of x and y

What can you use to find the y-intercept besides the point-slope form?

• Quadratic Formula

• Logarithmic Form

• Slope-Intercept Form

• Exponential Form
