Use the formula for a slope:
Slope=m=
Use the formula for a slope:
Slope=m= [plug-in the values and solve]
Slope=m=
Slope=m=
or
Slope=m=
.
Next, use the slope-intercept equation of a line: y=mx+b
y=mx+b [plug-in the values and solve for the b-term]
4=(-1/2)(-2)+b
4=1+b
4-1=b
3=b
.
Plug the slope and intercept into the formula
y=mx+b
y=-1/2x+3
