What is the point-slope form of a line that has a slope of 3 and passes through point (1, 4)? y minus 4 = 3 (x minus 1) 1 minus y = 3 (x minus 4) y 1 minus 4 = 3 (1 minus x 1) 1 minus y 1 = 3 (4 minus x 1) I NEED IT NOW PLEAS

y - 4 = 3(x - 1)

Step-by-step explanation:

It looks like you have slope 3  and a point (1, 4)

so  it should be  y - 4 = 3(x - 1)

which is your first choice:  y minus 4 = 3 (x minus 1)
