write the slope-intercept form of:
y=mx%2Bb where m is a slope and b is y-intercept
a slope:m=+1%2F2,
y-intercept:+b=+-3
y=%281%2F2%29x-3


and
y=mx%2Bb
m=2
point (-1, 3)
y=mx%2Bb .........substitute slope and coordinates of given point to calculate y-intercept b
3=2%28-1%29%2Bb
3=-2%2Bb
3%2B2=b
b=5
then,
y=2x%2B5
