The point (1,8) and has a slope of 3 what is the equation of the line ?

Question

y=?

Answer 1

y = mx + b if the format for the equation of a line in slope intercept form

m given as 3, (x,y) given as (1,8).

plug values into equation and solve for b:

8 = 3(1) + b

b = 5

y = 3x + 5 is equation of the line
