Title: Do these equations represent the same line Post by: whill40 on Apr 13, 2020 y+3 = (x-8) point slope form
y = -3/4x + 3 slope intercept form 3x + 4y = 12 standard form Title: Re: Do these equations represent the same line Post by: bio_man on Apr 13, 2020 They represent the same line if they have the same slope and y-intercept. For that, it's best to rearrange the equations in slope y-intercept form.
FIRST y+3 = (x-8) y = x - 8 - 3 y = x - 11 Slope of 1, y-intercept of (0,-11) SECOND y = -3/4x + 3 Slope of -3/4, y-intercept of (0,3) THIRD 3x + 4y = 12 4y = -3x + 12 y = -3/4x + 12/4 y = -3/4x + 3 Slope of -3/4, y-intercept of (0,3) |
