Which of the following equations show the relationship between x and y in the table? 1. y= x+3
2. Y= 3x+1
3. Y=2x+2
4.y=4x

y=2x+2

Step-by-step explanation:

you have to substitute x and y in the given equations and which one works

for y=x+3 , 4=1+3 true , 6=2+3 false

for y=3x+1, 4=3*1+3 false

for y=2x+2, 4= 2*1+2 true, 6= 2*2+2 true, 8= 2*3+2 true, 10=2*4+2 true

for y=4x, 4=4*1 true, 6= 4*2 false

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
