i know how to put the solutions on the graph. i am stuck on this equation.

i think x=0 but i can not figure for y. please help me and show me the steps to solve this.

**jai**, Saturday, August 21, 2010 at 12:44pmfirst solve for y:

35-5y=0

-5y=-35

y=7

*you can actually rewrite this as:

0x + y = 7

notice the equation has a definite value of y (which is 7) while you can substitute any number on x (since when it is multiplied by zero, the product is always zero),, y is therefore independent on the value of x,,

therefore, the graph of y=7 is a horizontal line passing through the y-axis at point (0,7), and will never pass at the x-axis,,

so there,, =)
