# Math Help - Graphing systems of equations?

1. ## Graphing systems of equations?

I'm graphing systems of equations...and I am not sure how to do this math problem...y = x squared + 4x +1 and -3x + y= -1 so far I've got -3x+x squared minues x squared plus 4 x plus 1 because I distributed the y = in -3x+y = -1 what should I do next, please help! Any tips would also be helpful. thanks.

Directions: Solve the following systems of equations algebraically using either the substitution method or elimination method..

2. I am not sure how to do this math problem...y = x squared + 4x +1 and -3x + y= -1
$y = x^2 + 4x + 1$

$-3x + y = -1$
solve for y ...
$y = 3x - 1$

use the method of substitution ...

$3x-1 = x^2 + 4x + 1$
$0 = x^2 + x + 2$

since $b^2 - 4ac < 0$, the last equation has no real solution ... in other words, the graphs of the original parabola and line do not intersect.
