Question

What is the solution to the system of equations?

3x + 2y = 15
y - 4x = 2
(a) Use the substitution method to find the solution.
(b) What do you know about the two lines in this system of equations (Hint: Do
parallel? Are they the same line?)
they intersect? Are they
iswer:

Answer 1

3x+2y=15 : y=-3/2x+15/2

y-4x=2 : y=4x+2

they are not parallel lines

Explanation:

formula:

y=mx+b
