We know Slope-Intercept Form follows eqn-----> y=mx%2Bb
wheresystem%28m=slope%2C+b=yIntercept%29
As given, y=%281%2F2%29x%2B3
The Slope=m=1%2F2
yIntercept=3
In order to find out the x & y intercepts of the eqn,
let f%28y%29=0:
0=%281%2F2%29x%2B3
%281%2F2%29x=-3--->x=2%2A-3
highlight%28x=-6%29
Also, let f%28x%29=0
y=%281%2F2%290%2B3
highlight%28y=3%29, as shown already "b"
So, when we graph it;
Now, for the Slope=m=1%2F2=Rise%2FRun
On the "Rise", meaning "up" or "down" on the y-axis.
The "Run" meaning "left" or "right" of the x-axis. In this case, from y-intercept of "(0,3)", next point will be "1" up or down and "2" left or right.
Do the same also for the x-intercept of (-6,0)
