Question

What is the equation in point-slope form of the line passing through (2, 5) and (–1, 8)?
Answer
y – 5 = –1(x – 2)
y + 8 = –1(x – 1)
y + 5 = 1(x + 2)
y – 8 = 1(x – 2)

Answer 1

first one
do the slope formula

Answer 2

THE Y1-Y2=M (X1-X2)?

Answer 3

no it is y -Y = m(x-X) [ X & Y are coordinates of one of the 2 points]
m=(Y2 - Y1)/(X2 - X1)

Answer 4

It is the first one.
