What is the equation of the line that passes through the point (6,1) and is parallel to the line x+3y=15
Elden [556K]

9514 1404 393

Answer:

  x + 3y = 9

Step-by-step explanation:

The parallel line will have the same x- and y-coefficients. The new constant can be found by using the (x, y) values of the given point.

  x + 3y = (6 +3(1)) = 9

The equation of the parallel line is ...

  x + 3y = 9

Find the value of y so that the points (-5,10) and (3,y) lie on a line with slope -3/8.
shtirl [24]

Answer:

y = 7

Step-by-step explanation:

calculate the slope m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 5, 10) and (x₂, y₂ ) = (3, y)

m = \frac{y-10}{3+5} = \frac{y-10}{8}

For this to equal - \frac{3}{8}

since the denominators are equal, equate the numerators

y - 10 = - 3 ( add 10 to both sides )

y = 7
