You can put this solution on YOUR website! -3 x + 5 y = -5
y= 3/ 5 x -1
3x-y=8 6x-2y=8
Assume values of x and plug in the equation to get values of y.
Plot the points
x 0 5 10
y= -1 2 5
(x,y) ( 0 , -1 ),( 5 , 2 ),( 10 5 )
You can put this solution on YOUR website! -3x+5y=-5
Three Steps
...
Step One: solve for y
5y = 3x - 5 ==> divide both sides by 5
y =
...
Step Two: Find intercepts (these will provide two line coordinates, which you can draw a line through for the graph)
y intercept
Comparing to the y=mx+b (slope intercept) format, the y intercept is -1;
therefore, plot (0, - 1)
x intercept
Set the equation equal to 0 (or the y value as zero) and solve for x
0 =
1 = x
x=
therefore, plot (, 0)
...
Step Three: Find more line coordinates
Choose any value for x and then solve for y, these are additional line coordinates.
If you choose x = 5
y =
plot (5, 2)
If you choose x = -1
y =
plot (-1, )
