Answer:
Slope:
Y-Intercept:
Step-by-step explanation:
1. To find the slope, we need to have the equation in slope-intercept form, which is . In this case, our equation is already in this form.
is what your slope is. In this case, our
2. To find the y-intercept we look at value that is in
. In this case,
is
. So, our ordered pair is
.
We have that
<span>y=-1/3(x+2)</span>²<span>+5
using a graph tool
see the attached figure
we know that
1) the graph open downward
2) the vertex of the graphic is the point (-2,5)
3) the axis of symmetry of the graph is x=-2
4) the x intercept values are (-5.873,0) and (1.873,0)
5) the y intercept value is (0,3.667)
