Hi nearlyhairless, lets see what we can do to:
Are the following lines parallel, perpendicular, or neither? L1 with equation x – 6y = 30 L2 with equation 6x + y = 6
Put the equations in slope intercept form:
, m=slope and (0,b)= y-intercept. Parallel lines have equal slopes and perpendicular lines have slopes that are negative reciprocals (opposite signs and upside down).
Given g(x) = 4x – 3, find g(3a).
Given f(x) = 4x + 4, find f(0)
Solve the system by addition.
L1) 5x – 3y = 13
L2) 4x – 3y = 11
Multiply L2 by -1 and add L1 and L2
Substitute x=2 into L1 and solve for x.
The solution is (x,y)=(2,-1)
