Answer 1

B. (2,5).

Answer 2

There's a cool graphing calculator site. Just put in the equations, it graphs it. I like it a lot. You should check it out. It's easy to use.

Answer 4

Problem:
Solve −5x+y=−5;−4x+2y=2
Steps:
I will try to solve your system of equations.
−5x+y=−5;−4x+2y=2
Step: Solve−5x+y=−5for y:
−5x+y+5x=−5+5x(Add 5x to both sides)
y=5x−5
Step: Substitute5x−5foryin−4x+2y=2:
−4x+2y=2
−4x+2(5x−5)=2
6x−10=2(Simplify both sides of the equation)
6x−10+10=2+10(Add 10 to both sides)
6x=12
6x6=126(Divide both sides by 6)
x=2
Step: Substitute2forxiny=5x−5:
y=5x−5
y=(5)(2)−5
y=5(Simplify both sides of the equation)
Answer:
y=5 and x=2
