HELPPPPPP PLEASE ! solve each system by graphing Y=1/2x+7 Y=3/2x+3
you use the y intercept to figure out where in the y-axis the slope will intercept.
Then you use rise over run to plot the slopes
are you sure there aren't any inequalities?

@Jamierox4ev3r
need help with number 11?
do you still need help?

\[\large y=\frac{1}{2}x+7\]\[\large y=\frac{3}{2}x+3\] Our equations are given in slope-intercept form: \[\large y=mx+b\] The \(\large b\) value is the y-intercept. It's where we cross the y-axis. So for our first equation, we see that the line crosses the y-axis at y=7.|dw:1369394055237:dw|
To draw the line, we'll need another point where it crosses. We can either find the x-intercept, or simply plug in a value for x to find another point.
let's plug in \(\large x=2\). \(\large y=\dfrac{1}{2}(2)+7\) Which gives us, \(\large y=8\) So that gives us another cooridnate point (2,8).|dw:1369394257023:dw|
