Question

find the slope of the straight line x+2y=6​

Answer 1

Answer:

Well the easiest way to graph a 2d line is to put it in the form

y=mx+b

This form is so useful because b is the y intercept of the graph and m is the slope of the graph.

So the first thing you would do is solve for y

x+2y=6

2y=−x+6

y = −12x+3

So first of all we can see that the y intercept is y = 3, which means we can plot the point (0,3). We can see also see that the slope is -1/2 . Since slope is riserun

, we know that for every one space on the x axis you move the line moves down half a space. So the line would look like this
