Graphically determine the solution to the systems
1. y=2x^2-12x+19,y=2x-1
----
For the parabola y = 2x^2-12x+19, pick values for x and find y.
Plot the points and draw the curve thru them.
y = 2x-1 is a straight line, so 2 points are needed
The intersections are the solutions.
================
There are several FREE graph softwares online.
I use www.padowan.dk
=================
2. y=x^2-2x+8,y=x-7
Same as #1
---------------
3. y=x^2+5x-7, y=2x^2=2x+3
If you meant x^2+5x-7, y=2x^2-2x+3 it's 2 parabolas.

1. ,

as you can see, intersection points are (,) and (,)
so, solution is:
,
,

2. ,

there is no intersection point(s), so there is no real number solution

3. , (assuming you have that)

as you can see, there is no intersection point(s), so there is no real number solution
