write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the
Brilliant_brown [7]
  • Parallel lines have the same slope but different y intercepts.
  • turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
  • divide the equation by -1 in order to make y positive and you get y=x-7
  • So rewrite the equation with the same slope but this time solving for b
  • y=x+b
  • plug in your coordinates
  • 0=1+b
  • subtract 1 from both sides
  • -1=b
  • so your equation would be
  • y=x-1
