find the slope or change in y over change in x. This is (4-3)/(0-(-2))=1/2
point-slope formula y-y1=m(x-x1)
y-4=(1/2)(x-0)
y-4=(1/2)x
y=(1/2)x+4

Find the equation of the line containing the points
(-2,3) and (0,4)
slope:
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m=%284-3%29%2F%280%2B2%29
m=%281%2F2%29
y=mx%2Bb
y=%281%2F2%29x%2Bb.......from the point (0,4) we know that y-intercept b=4
y=%281%2F2%29x%2B4
