Question

graph -x - 2y = 6.


can anybody do this?!

Answer 1

Try to do that for youself. If you cant then ask

Answer 2

thats a line that intersects y axis at -3 and has a negative inclination of 0.5

Answer 3

i dont understand how to do it.

Answer 4

im trying not to give you the answer but help you understanding the method instead.

Think with me, lets solve it for Y

-2y = x +6, right? Now lets get rid of the "minus" signal. Multiply both members of equation by (-1)

2y = -x -6

Not devide both members by (2)

y = -0.5 -3


now you have it in the y = M.x + B format.

Where M is the inclination = -0.5 and B = y axis intersection = -3


Now draw the point (0, -3)

And now you can give a number to X and find its Y, example:


If X = 2, then:

y = 0.5 * 2 -3
y = -2


Now draw the point (2, -2)

if X = 4, then:

y = 0.5 * 4 -3
y = 2-3 = -1

Now draw the point (4, -1)

and now that you have 3 points, just draw a line between them
