What is an equation of the line that passes through the point (-5,-3)(−5,−3) and is parallel to the line 3x+5y=15
Sunny_sXe [5.5K]

Answer:

  • y = -3/5x - 6 or 3x + 5y = -30

Step-by-step explanation:

<u>Given line:</u>

  • 3x + 5y = 15

<u>Converting into slope-intercept form:</u>

  • 3x + 5y = 15
  • 5y = - 3x + 15
  • y = -3/5x + 3

<u>Parallel lines have the same slope, so the parallel line will be:</u>

  • y = -3/5x + b

<u>Using given point (-5, -3) finding the y-intercept:</u>

  • -3 = -3/5(-5) + b
  • -3 = 3 + b
  • b = -3 - 3
  • b = -6

<u>So the line is:</u>

  • y = -3/5x - 6

<u>Or converted into standard form:</u>

  • y = - 3/5x - 6
  • 3/5x + y = -6
  • 3x + 5y = -30

If y=5x-3 and 3x-y=-1, what is the value of y
Svet_ta [14]
Well if you make them both equal to y I got...
Y=-3x+1
Y=5x-3
But I don't think you can find it without the y since they are different variables. Like I know -3x and 5x are the slopes and 1 and -3 are the y intercepts but I'm stuck after that. Sorry if that wasn't any help.
Hope I helped.
