<span>You divide the top of the fraction by the bottom and t<span>hen multiply it by 100.
Example : 1/4
-you do 1 divied by 4 = 0.25
-then you mutiply 0.25 by 100
-and you will get : 25%
-Hope this helps.</span></span>

multiply first equation by -2 and add to 2nd equation
-4x-6y=4
<u>4x+7y=-6 +</u>
0x+1y=-2
y=-2
sub back
2x+3y=-2
2x+3(-2)=-2
2x-6=-2
2x=4
x=2
(x,y)
(2,-2)
<span>Since you already have the equation in y = mx + b form, which is called the slope-intercept form, with m = slope and b = y-intercept, you can graph it easily with that information. The 3 is the y-intercept. That means point (0, 3) is where the line crosses the y-axis. Plot that point first. The slope, m = -(1/5). The slope is the rise (up or down) over the run (left or right), or rise/run. -(1/5) can be thought of (-1)/5 or as 1/(-5). Both ways are correct and work. After plotting (0, 3), using m = (-1)/3, start at (0, 3) and count one unit down, and three to the right. That's a second point on your graph. If you want a third point, you can go back to the original point, (0, 3), and now use the slope as 1/(-5). That is, from (0, 3), go 1 unit up and 5 to the left. That is a third point. Now draw a line through all three points. </span>I hope that this is the answer that you were looking for and it has helped you.
