Question

10x-4y=3, and 5x-2y=6 how would I solve to graph?

Answer 1

find out what each value stands for and then you can write it as a coordinate...

10x-4y=3 and 5x-2y=6

set each to y=...

-4y= -10x+3 and -2y= -5x+6

solve...

y= 5x/2 -3/4 and y= 5x/2 -3

since they have the same slope but different intercept that means that there is no answer

there would be and answer if they intersected...

darn trick questions :)

Answer 2

Solve the equations for y, then you have the linear equation

y=bx+c where b is the slope and c is the y-intercept.  For your equations you would get y=5/2x-3/4 and y=5/2x-3

You could also use the table method:

   x   |   y

~~~~~~~~~

   1   |   7/4

etc.  Plug in various values for x, then solve for y and create a table.  You can then graph each of those points and draw a line through them.

Answer 3

pay attention to your high school math courses would be the best way  

Answer 4

You need to put the equations in y=mx+b form.

Leave "y" by itself. Move 10x to the other side and it becomes a negative.  -4y=-10x+3  

Add 4 to each number.  y=-6x+7

Graph y=-6x+7

Leave "y" by itself. Move 5x to the other side and it becomes a negative.  -2y=-5x+6

Add 2 to each number.  y=-3x+8

Graph y=-3x+8
