Explanation:
- The equation for slope-intercept form is
#y=mx+b# - Plug in the points and the slope into the correct spots.
#(2,3)# #x=2# ,#y=3# #m=-1/2# #3=-1/2(2)+b# - Solve for b (the y-intercept)
#3=-1+b# Add one to both sides to balance equation#4=b# #y=mx+b# ,#y=-1/2x+4# - Check answer by graphing
