Question 1036855: Write an equation in slope-intercept form of the line whose parametric equations are x = k + 4 and y = 2k - 1.
y = 2x - 9
y = 2x + 7
y = 2x - 7
y = 2x + 9

+x+=+k+%2B+4+
+k+=+x+-+4+
and
+y+=+2k+-+1+
+2k+=+y+%2B+1+
+k+=+%281%2F2%29%2Ay+%2B+1%2F2+
---------------------
+x+-+4+=+%281%2F2%29%2Ay+%2B+1%2F2+
+2x+-+8+=+y+%2B+1+
+y+=+2x+-+9+
--------------------
check answer:
+y+=+2x+-+9+
+2k+-+1+=+2%2A%28+k+%2B+4+%29+-+9+
+2k+-+1+=+2k+%2B+8+-+9+
+-1+=+8+-+9+
+-1+=+-1+
OK
