    Since you are given the slope and a point on the line, write the equation in the "point-slope" form, y-y₀ = m(x-x₀):

    y - (-5) = (2/3)(x - (-6))

    y + 5 = (2/3)(x + 6)

    That satisfies the requirements of the question, a linear equation with given slope and point, but since the required form of the equation is not specified, the equation can be restated in a number of different forms:

    Standard Form: Ax + By = C

    3y + 15 = 2x + 12

    2x - 3y = 3

    Slope Intercept Form:

    y = (2/3)(x + 6) - 5

    y = (2/3)x + 4 - 5

    y = (2/3)x - 1

    Slope is 2/3, y-intercept is -1

    Intercept Form:

    x/(3/2) + y/(-1) = 1

    (intercepts are x = 3/2 and y = -1

    A line with a slope of m = 2/3 

     and passes through the point (-6, -5)

     y = mx + b 

     -5 = (2/3)(-6) + b 

     -5 = -4 + b

    -1 = b

     The equation of the line:

     y = (2/3)x - 1

     y = (2x - 3)/3

    Line, L, say,  with slope m = (2/3) passes through P(-6,-5). Then equation of L in

    slope, y-intercept form is y = mx +b where m is the slope and b is the y-intercept.

    So y = (2/3)x + b. Now P(-6,-5) is on L. Then (-5) = (2/3)(-6) + b = b-4. Then b = -1

    and y = (2/3)x -1 is the slope, y-intercept form of the equation L.

    y - y1 = m(x - x1)

    y - (-5) = 2/3[x - (-6)]

    y + 5 = 2/3(x + 6)

    3(y + 5) = 2(x + 6)

    3y + 15 = 2x + 12

      3y = 2x + 12 - 15

     3y = 2x - 3

      y = 2/3x - 1 answer//

    Write a linear equation based on the following information: 

     A line with a slope of m = 2/3 and passes through the point (-6, -5)

     (y - -5) = (2/3)(x - -6)

     (y + 5) = (2/3)(x + 6)

     3(y + 5) = 2(x + 6)

     2x - 3y = 3

    The general form of a line:

    y = mx + b

    You are given an m, x, and y.  Substitute and solve for the remaining unknown:

    -5 = (2/3)(-6) + b

    -5 = -4 + b

    -1 = b

    Your equation is:

    y = (2/3)x - 1

    Point of passage: (-6, -5)

    Slope: 2/3

    Equation: y = (2/3)x -1

  • 1 year ago

    Solution to your problem is --

    Slope m of the line = 2/3

    Let the line be  y = mx + c

    => y = (2/3) x + c ................ (1)

    Since this line passes through (-6, -5 )

    =>  - 5 = (2/3) (-6)  +  c,  multiply both sides by 3

    =>  - 15  =  - 12 + 3 c 

    => - 3  =  3 c

    =>  c =  - 1

    Substitute this value of c in (1) above 

    =>  y  =  (2/3) x  -  1

    This first form is called the point-slope form. It is a good place to start if that is what you have, a point and the slope. From there you can change it to other forms.

    y + 5 = (2/3)(x + 6) ... point-slope form

    3y + 15 = 2(x + 6)

    3y + 15 = 2x + 12

    2x - 3y - 3 = 0 ... general form

    a line with a slope of 2/3 has an equation of 

    y = (2/3)x + k

    use the point to find k

    –5 =  (2/3)(–6) + k

    k = –5 + 4 = –1

    equation is

    y = (2/3)x – 1

    or

    3y = 2x – 3
