Answer 1

Which equation does the graph below represent?

A coordinate grid is shown. The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y axis values are from negative 10 to positive 10 in increments of 2 for each grid line. A line is shown passing through the ordered pairs negative 4, negative 8 and 0, 0 and 4, 8.

y = 2x
y = fraction 1 over 2x
y = fraction 1 over 2
y = 2 + x

Answer 5

the line passes at point \((0,0)\), so its equation has to be like this:
\(y=kx\)
furthermore, it passes at point \((1,2)\), so, after a substitution, the subsequent equation holds:
\(2=k\cdot 1\)
what is \(k\)?

Answer 6

b

Answer 7

please try to solve my equation above for \(k\)

Answer 8

ok i did the work and got c

Answer 9

we have:
\(k=2\) so after a substitution into the starting equation, I get:
\(y=kx=2x\)
so what can you conclude?

Answer 10

OHHHHHHHHH SO ITS ( D )

Answer 11

are you sure?
Please note that we have:
\(y=2x\)

Answer 12

OH OK ON THAT NOTE THEN I CHOSE a
