Parallel lines have the same slope.
9-6/k-3
3/k-3
The slope from the other must be
5y=7-2x
y= 7/5-2/5x
slope = -2/5
3/k-3=-2/5
15= -2 (k-3)
15= -2k+6
9= -2k
9/-2=k
a line has the equation 2x + 5y = 7. another line passes through (3,6) and (k,9). what value for "k" will make the lines parallel?
please tell me HOW to do this, too!
thanks!
