Question

Which is the equation of the line that contains points (0,5) and (5,8)? Which one would it be out of those 4?

Answer 1

point-slope form of a line is given by

y-y1 = m(x-x1). where m is the slope

m=(8-5)/(5-0) = 3/5

so using the first point gives us
y-5=3/5x

using second point gives us
y-8=3/5(x-5)

2nd answer choice. learn these linear formulas well, they never go away!!!!
