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

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
