Question

A line has a slope of 1/2 and passes through the point (6,2).

a) Write the equation of this line in point-slope form
(b) What is the y-intercept of this line?

Answer 1

a) y-2=1/2(x-6) b) The y-intercept of this line is -1.

Explanation:

y-y1=m(x-x1)

y-2=1/2(x-6)

------------------

y=1/2x-6/2+2

y=1/2x-3+2

y=1/2x-1

y=mx+b where m=slope and b=y-intercept.
