2.Describe how the graph of y=/x/ and y=/x+3/ are related.
A.The two graphs are the same
B.The graphs have the same shape. The y-intercept of y=/x/ is 0, and the x-intercept of the second graph is 3.
C.The graphs have the same shape. The y-intercept of y=/x/ is 0, and the y-intercept of the second graph is 3.
D.The graphs have the same shape. The y-intercept of y=/x/ is 0, and the y-intercept of the second graph is -3.

1.

First, isolate the slope of the given equation.

What must you do to the slope of the given equation in order to make a perpendicular slope for the second line equation? Solve for the 2nd slope.

Now that you have the 2nd slope, and a point on the 2nd line, use point-slope form to find an equation for the 2nd line.
