How do i write y = x -4 in a x and y chart/table?
IrinaK [193]
Okay well it kept saying that I for some reason was not using appropriate words so my long response got deleted.

tldr; we can treat this like a box that we put something into (x) and we get something back from it (y).

We can then take this data we get and put it in a table.  This is useful for finding patterns.

I will post a picture of what a table may look like.

Hope this Helps!

Change 5x - y = 3 into slope-intercept form.<br> © by – 5x+3
agasfer [191]

The slope intercept form is y=5x-3

Explanation:

The equation is $5 x-y=3$

Now, we shall bring the equation $5 x-y=3$ in the slope intercept form.

The general form of the slope intercept is given by

y=mx+c

Hence, we need to rewrite the given equation in this form.

Thus, we have,

$5 x-y=3$

Subtracting both sides of the equation by 5x, we get,

-y=-5x+3

Multiplying both sides of the equation by (-), we get,

y=5x-3

Thus, the slope intercept form of the given equation is y=5x-3
