Question

Which equation is the equation of the line in point slope form that has a slpe of 1.9 and passes through the point (4.5, -1.4)

A) Y-1.4=1.9(x-4.5)
B) Y-4.5=1.9(x-1.4)
C) Y-4.5=1.9(x+1.4)
D) Y+1.4=1.9(x-4.5)

Answer 1

D)
`y + 1,4 = 1,9(x - 4,5)`

Explanation:

According to the Point-Slope Formula,
`y - y_1 = m(x - x_1)`, all the negative symbols give you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT signs.
