Question

how would i graph y=-2x ?

Answer 1

what do you know about y=-2x?

Answer 2

slope = ?
y -intercept = ?

Answer 3

well to tell yhu i already did most of my homework on that its just i need help on 3 more including this one which are y=-x and y=2/3x + 4 so as yu can see all three of them are similar and thats what i need help on.

Answer 4

x=0; y=0 (0,0)
x=1;y=-2 (1,-2)
connect those to points

Answer 5

slpoe = -2 and intercept = 0
i think

Answer 6

The slope is -2. And with the slope defined as the rise over run, for each push in the positive x-direction the point will go DOWN by 2 in the y-axis. So start at (0,0), then at x = 1, y will equal -2. At x = 2, y will equal -4. For x = -1, y will equal 2. It can be said that for each point along the x-axis the y-value at that point will equal negative two times the x-value.

Answer 7

yes.
you can start the graph at 0 going downwards.
slope = y/x

so...

slope = -2/1

the graph should end up looking like a backward slash on your keyboard.

Answer 8

so down 2, right 1?

Answer 9

yes
