Y=-1/4x+13 not sure though
Answer:
3/4
Step-by-step explanation:
You can calculate slope with 
2 points from the graph are (0,-1) and (4,2)
plugging the points in would give you

Please rate me as brainliest if this helped!
Answer:
You can install ( Foto math) app then you can find it. Small help
The slope is -4. This is because of slope intercept form, y=mxtb. M= the slope so the slope in this case is -4
Answer:
see below
Step-by-step explanation:
The graph opens upward if the sign of the squared term is positive. If that sign is negative, the graph opens downward. The first three equations open upward; the last opens downward.
The line of symmetry is the value of x that makes the squared term zero. Here, that is x=5 for all equations.
<u>y=2/3(x-5)^2</u>: A, D
<u>y=1/2(x-5)^2</u>: A, D
<u>y=3/4(x-5)^2</u>: A, D
<u>y=-4(x-5)^2</u>: B, D
