Question

What is the point-slope from of a line that has a slope of 3 and passes through point (1,4)

Answer 1

y-4=3(x-1)

Explanation:

y-y1=m(x-x1)

Plug in m=3:

y-y₁=3(x-x₁)

Plug in the points into x₁=1 and y₁=4:

y-4=3(x-1)

Answer 2

y-4=3(x-1)

Explanation:

Point slope formula is attached in an image below.

1) Plug in 3 as m in point slope form:

y-y₁=3(x-x₁)

2) Plug in the points into x₁ and y₁:

y-4=3(x-1)
