Question

**URGENT: Is the relationship shown by the data linear? If so, model the data with an equation.

X Y
1 5
5 10
9 15
13 20

Answer 1

No, they are not linear, because when you graph them they do not form a straight line.

Answer 2

x
1 5 9 13
= 1 1+4 1+2*4 1+3*4

Answer 3

@IMStuck what about

X Y
1 -4
7 -7
13 -10
19 -13

Answer 4

@amoodarya THANK YOU!!! :)

Answer 5

try
to write a line between (1,5) and (5,10)
and check another points
it is a linear relation
if you draw points
\[m=slope=\frac{ 10-5 }{ 5-1 }=\frac{ 5 }{ 4 }\\y-y0=m(x-x0)\\y-5=\frac{ 5 }{ 4 }(x-1)\]

Answer 6

in the second case
it is a linear relation between points

write a line equation between (1,-4) and (7,-7)
y-(-4) =4/6 (x-1)
