Answer:
no solution
Step-by-step explanation:
the solution to a system of equations is at the points of intersection of the 2 lines.
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 4 ← is in slope- intercept form
with slope m = 
y =
x - 1 ← is in slope- intercept form
with slope m = 
• Parallel lines have equal slopes
then the 2 lines are parallel and never intersect.
Thus the system of equations has no solution
Answer:

Step-by-step explanation:


Let's solve for
in the first equation and then solve for
in the second equation.
I will then use the following identity to get right of the parameter,
:
(Pythagorean Identity).
Let's begin with
.
Subtract 2 on both sides:

Divide both sides by -3:

Now time for the second equation,
.
Subtract 1 on both sides:

Divide both sides by 4:

Now let's plug it into our Pythagorean Identity:




Three that are equivalent are 12:9 8:6 28:21
