Use the "slope-intercept" form to determine the slope remembering that parallel lines have identical slopes.
Slope-intercept form:
y+=+mx%2Bb where m = the slope and b = the y-intercept.
1) y+=+0.5x%2B4 Here, m = 0.5 and b = 4.
2) y+=+6 Here m = 0 and b = 6.
3) 7x-y+=+5 Rearrange this to:
y+=+7x-5 m = 7 and b = -5.
4) y+=+4x-8 Here m = 4 and b = -8
