Answer:
Look below :)
Step-by-step explanation:
Well one of them is a bigger percentile, so the difference is 32-15. So the answer is 17. I hope this helps!
You have to use the y2-y1 over x2-x1.
So, let's plug the numbers in.
(-3,-3)
^ ^
X1 Y1
(4,0)
^ ^
X2 Y2
So, that would be
0-(-3)
——
4-(-3)
The two subtraction signs counteract and become a positive, or addition symbol. So it would be
0+3
——
4+ 3
Do the addition to get 3 over 7 or
3
—
7
Answer <u>(assuming the question allows it to be written in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula 
, substitute the given points' x and y values, and simplify:
Thus, the slope is 
.
2) Now, use the point-slope formula 
and substitute real values for 
, 
, and 
.
Since represents the slope, substitute in its place. Since and represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:
Answer:
k = -2
Step-by-step explanation:
f(x) = (x − h)² + k
(h, k) is the (x, y) coordinate of the vertex
For a vertex of (4, -2)
h = 4
k = -2
