Question

Write the point-slope form of an equation of the line through the points (6, -1) and (5, -7).

A. y−5=6(x+7)
B. y+1=6(x−6)
C. y−6=6(x+1)
D. y+7=6(x+5)​

Answer 1

B. y + 1 = 6(x - 6)

Explanation:

First, find the rate of change [slope], then insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE term of what they really are.
