Question 621075
What would the graph for the equation 4x-5y=12
Why not plot the graph and see
Put the equation into the slope intercept form, y = mx + b
4x - 5y = 12
Subtract 4x from both sides
-5y = -4x + 12
y has to be positive, mult both sides by -1
5y = 4x - 12
Divide both side by 5
y = {{{4/5}}}x - {{{12/5}}}
Decimals
y = .8x - 2.4
Plot at least 3 points, x=-2, x=0, x=8, I chose those that gave us integers for y but you can choose what ever you want
Substitute for x and find y for each point, a table will look like this
 x | y
-------
-2 |-4
 0 |-2.4
+8 |+4
:
The graph will look like this
{{{ graph( 300, 200, -10, 10, -10, 10, .8x-2.4) }}}
