Determine whether the lines are parallel, intersect, or coincide<br> y=1/3x+4 <br> x-3y=-12
adell [148]

The slopes of two lines are equal which means that the lines are parallel.

Further explanation:

The slopes of lines are used to find the relationship between two line.

  • If two lines are parallel, then their slopes will be equal.
  • If two lines are perpendicular, the product of slopes of both lines will be -1

The standard form of equation of line is:

y=mx+b

The coefficient of x is the slope here.

y=1/3x+4

Let m1 be the slope of first line:

m_1=\frac{1}{3}

x-3y=-12\\-3y=-x-12\\-3y=-1(x+12)\\3y=x+12\\\frac{3y}{3}=\frac{x+12}{3}\\y=\frac{x+12}{3}\\y=\frac{x}{3}+\frac{12}{3}\\y=\frac{1}{3}x+4

Let m2 be the slope of second line

m_2=\frac{1}{3}

We can see that:

m_1=m_2

The slopes of two lines are equal which means that the lines are parallel.

Keywords: Parallel Lines, Perpendicular Lines

Due very soon! Please help
RUDIKE [14]

Answer: y=-5/4x+7

Step-by-step explanation: You can see, by looking at the graph, that the slope will be negative, so you can eliminate the options with a positive slope. You can take the first point (0,7) and the second point (4,2) and calculate the slope (the change in y divided by the change in x). 7-2 is five, so that gives us our numerator of the slope. 0-4 is -4, so that gives us our denominator. That gives us a slope of -5/4, so the only answer with that slope is the third option, y=-5/4+7. I hope this helps!
