Question

What is a point-slope equation of the line with slope -10 that goes through the point (1,4)

A. y-4=10(x-1)
B. y-4=1-0(x-1)
C. y+4=-10(x+1)
D. y+4=10(x+1)

Answer 1

B. y - 4 = -10(x - 1)

Explanation:

According to the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs.
