Question

Which is the equation of the line with slope 3 that contains point (-1, 5)?

Answer 1

Y - 5 = 3 ( x + 1 )

i am a mathematics teacher. if anything to ask please pm me

Answer 2

The expression above is in a point-slope form which is:

y-y1 = m(x-x1)

Therefore, from the given problem:

m =  3
y1 = 5
x1 = -1

The transformed equation would be:

y-5 = 3(x+1) which is the first choice.
