    3.5 = -3.5x 3.5 / -3.5 = x x = -1

    There is no solution. They are parallel.

    They are parallel, they have the same slope. They just have different y-intercepts.

    No, if they are parallel the set has infinite solutions.

    I suggest using geogebra.

    Solution means intersecting points.

    There are no intersecting points in parallel lines.

    this is algebra 1. So no solution?

    A dependent system of equations is a system with __________. the same line parallel lines intersecting lines and lines that have the same equation intersecting lines and lines that have the same slope

    Dependent system of equations are the same line.

    Independent system of equations intersect one another, as opposed to dependent. And yes, it's A.

    Solve the system of equations. x + 3y = −1 2x + 2y = 6 (−4, 1) (2, −1) (4, −1) (5, −2) @izuru

    Like, it's the exact same problem. I couldn't find it but I'll still help you out lol So you can use substitution in this one. Try and isolate x in the first equation.

    -3y and -1 are not like terms.. So it's just x = -3y -1. Now, plug that isolated x into the second equation. 2x + 2y = 6 2(-3y - 1) + 2y = 6

    You have to distribute 2*(-3y - 1) before adding +2y.

    The equation turns into -2 -6y + 2y = 6. You multiply 2 by -3y and -1.

    y = -2. Plug it in with the first equation to figure out the value of x.
