y=mx+b is slopeintercepf rom
m=slope
b=yintercept
so to find the slope
find how many units the line goes up for every how many units it goest to the right
goes about 1 unit up for every 2 units to the right
so slope is 1/2
y=1/2x
y intercept is hwere the line crosses the y axis
it crosses at -1
y=1/2x-1
convert 1/2 to deimal since dats the qustion
1/2=0.5
y=0.5x-1
