Hi

Using the standard slope-intercept form for an equation of a line y = mx + b 
 *[tex \LARGE\ where \ m \ is \ the \ slope \ and \ b \ the \ y-intercept]
Line with slope=3/4 and y-intercept=8  then y = (3/4)x + 8
Line with slope=0.5 and passing through (-1,7)
  y = .5x + b  |using ordered pair (-1,7) to solve for b
  7 = -.5  b
  7.5 = b
 Y = .5x + 7.5
