When a point is reflected across the x-axis, it's y value is flipped. Here is a formula for your future reference:
X-axis reflection: (x,-y)
Using your given coordinates, you simply plug the numbers in, resulting in final coordinates of (5,3.5).
Because the problem asks for the distance between the two points, you now have to find the difference between -3.5 and 3.5, which is 7.
There you go; the distance between the points is 7 units.
Answer:
in graph A the vertex is (0,0)
in graph B the vertex is (0,3)
in graph C the vertex is (0,-3)
And in graph D the vertex is (0,-1)
The axis of symmetry for all of the is 0
And i don't remember maximum and minimum sorry
Answer:
the function is a y-intercept
Step-by-step explanation:
y=mx+b is the slope intercept formula, m being the slope and b being the y-intercept, meaning y=b, so b=-9/4.
Because it says y=-9/4, we can assume that m, or the slope equals 0.
so when you plug it in, you get
y=0x-9/4
y=-9/4
Answer:
a(3x-8)=0
a=0 and b=8/3
Step-by-step explanation:
This second line is not necessarily true. We could have a=0 OR x=8/3. They don't both have to be 0.
