Find (a) the equation of a line that is parallel to the given line and includes the given point, and (b) the equation of a line that is perpendicular to the given line through the given point. Write both answers in slopeintercept form. (c) Graph both of these lines on the same axes and submit your graph. Please show all of your work.
y = 2x + 3, (2, 3)

Just use the pointslope form and then rearrange terms to slopeintercept form:
The line through (2,3) with slope 2:
(y(3))/(x(2)) = (y+3)/(x+2) = 2
The other line has slope 1/(2) = 1/2.
Go for it.
