y
= 5 - x2
y = x + 3 |
|
| Start
with quadratic equation. |
y
= 5 - x2
In standard form this is:
y = -x2 + 0x + 5 |
|
Find
the axis of symmetry. |
x
= -b/2a
x = -(0)/2(-1)
x = 0/(-2)
x = 0 |

Graph
the parabola. |
 |
|
Find
the slope and y-intercept of the line. |
y
= x + 3
slope =
1
y-intercept
= 3 |
|
Graph
the line. |
y
= 5 - x2
y =
x + 3 |
|
Find
the points of intersection. |
