Question

find the solution of the equation 2x+4y=9​

Answer 1

Answer:

How do I find the x intercept of the graph of the equation . 2x - 4y = 9?

Just put y = 0

So it's 2x = 9

X = 9/2 which is x intercept

The easiest way to analyze a linear equation is to first put it into very similar form: y=mx+b, where m is the slope or coefficient of x-term and b, is a constant.

Let us do that:

2x-4y=9

2x=9+4y

2x-9=4y

or,

y=(1/2)x - (9/4)

1/2 is the slope and -9/4 is the constant b

Now the next step is to find the x-intercept i.e where our line touches the x-axis:

our line touches the x-axis (assuming that it has an x-intercept) when y=0

so:

0=1/2x -9/4

solving for x:

x=9/2

That’s it!
