Inverse variation
y=k/x
k=konstant
(x,y)
x=2
y=8
8=k/2
mult 2
16=k
(x,3)
3=16/x
mult both sides y x
3x=16
diivide 3
x=16/3
(16/3,3)

The quadratic function, y = x2, has an x-intercept at the origin = TRUE</span>
<span>
The quadratic function, y = x2 + 3, has an x-intercept at the origin = FALSE</span>

From x = -2 to x = 0, the average rate of change for both functions is positive = FALSEWhen viewing a graph, you start from the left and go to right and from left to right from -2 to 0 the graph is declining.

From x = -2 to x = 0, the average rate of change for both functions is negative = TRUEBoth are declining if you read the graph from left to right.

For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function. = FALSE</span><span>
y = x^2
If we insert 2 into y = x^2 we get y = 4 but our point (2,3) has y = 3
</span>
For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function. = TRUE
If we insert 2 for x, we see that y = x^2 + 3 = y = 2^2 + 3 = y = 7 and our y value in the point (2,7) is 7.
Answer:
y=-3x+2
Step-by-step explanation:
to find slope: 5--4/-1-2
5+4=9
-1-2=-3
9/-3=-3
y-5=-3(x+1)
y-5=-3x-3
y=-3x+2
