What is the equation in slope-intercept form of the line that passes through (1,5)and has a slope of 3 ?

Answer 1

y = mx + b
5 = 3(1) + b
2 = b
and m =3

y=3x + 2

Answer 2

since you are given a point and a slope, start with the point-slope form:

y-5 = 3(x-1)

Now just rearrange things to get what you need.
