X=-4 that might be the correct awnser
Answer:
The constant of proportionality is 1.5 and the value of q is 9.
Step-by-step explanation:
Assume Hours as 'x' and Miles walked = 'y'
Constant of proportionality means the same value of 
is maintained throughout.
So, note that 
= 1.5
This means that 
should also equal 1.5.
= 9.
Therefore, the value of 'q' is 9.
Answer:
Fourth option y = x²
Step-by-step explanation:
It is clear from the graph that parabola passes through origin, which is it's vertex and line of symmetry is y-axis.
So the equation of the parabola will be y = (x - 0)² + 0
This equation of the parabola is in the vertex form [ y = (x - h)² + k]
Therefore, equation of the parabola will be y = x²
This equation is true for the given values of x and y in the table.
For (-2, 4) ⇒ 4 = (-2)²
For (-1, 1) ⇒ 1 = (-1)²
Fourth option y = x² is the answer.
