Write in the line in slope-intercept form given the slope of 1/3, through the point (-6,9)
JulsSmile [24]

Answer:

<h2>         y = ¹/₃x + 11 </h2>

Step-by-step explanation:

A line passing through point (x₁, y₁) with the slope of m in point-slope form:

 y - y₁ = m(x - x₁)

m = ¹/₃

(-6, 9)      x₁ = -6,  y₁ = 9

So:

y - 9 = ¹/₃(x - (-6))

y - 9 = ¹/₃(x + 6)     ←    point-slope form

y - 9 = ¹/₃x + 2        {add 9 to both sides}

y = ¹/₃x + 11        ←  slope intercept form

The sum of three numbers is 83. The second number is 5 less than the first. The third number is 2 times the first. what are the
coldgirl [10]

Answer:

22, 17, and 44.

Step-by-step explanation:

So what you do is you will have three equations that we will put together.

1. x. The first number is x because they don't give us anything about it.

2. x-5. It says that the second number is 5 less than the first number.

3. 2x. It says that the third number is 2 times the first number.

<em>x+x-5+2x=83. </em>

<em>4x-5=83.</em>

<em>4x=88.</em>

<em>x=22. </em>

That is the first number. To find the second and third, you will plug 22 into the x.

2. 22-5=17.

3. 2(22)=44.

22, 17, 44 are your answers.
