Question

Graph each equation and tell whether it is linear.

Answer 1

\[1.) y=-2x \]

Answer 2

\[2.) y=0.5x+1\]

Answer 3

y=-2x is linear since it's in the form y = mx + b where m = -2 and b = 0

Answer 4

to graph y=-2x, you need 2 points

y=-2x

y=-2*0 .. plug in x = 0

y = 0

So one point on y=-2x is (0,0)

Answer 5

y = -2x

y = -2*1 ... plug in x = 1

y = -2

And another point on y=-2x is (1,-2)

Answer 6

so you now have (0,0) and (1,-2)

Plot them and draw a straight line through them to graph y=-2x

Answer 7

You do the same thing for the second equation

Answer 8

okay thanks(:

Answer 9

sure thing
