Write an equation in standard form of the line that passes through the given point and the given slope. (-9, -4); m = -1/3
tigry1 [53]
<h2>Answer:</h2>

First, we must determine <u><em>b</em></u> using <u><em>slope-intercept form*</em></u>, the given point, and the given slope.

-4 = -\frac{1}{3}(-9) + b\\\\-4 = -3 + b\\\\-1 = b

Second, we need to set up the equation of the line in slope-intercept form.

y = -\frac{1}{3}x - 1

Third, we convert the above equation to <em>STANDARD FORM**</em>.

y = -\frac{1}{3}x - 1\\\\\frac{1}{3}x + y = -1

We now have our equation: \frac{1}{3}x - y = -1

*Slope-intercept form: <em>y = mx + b</em>

**Standard form: <em>ax + by = c</em>

Which of the following statements must be true about the diagram? Check all that apply.
Ray Of Light [21]

Answer:

x + y = w

w > x

w > y

Step-by-step explanation:

x and y are interior angles of a triangle.

w is the exterior angle ( opposite to angles x and y ) of a triangle.

There is a formula that exterior angle of a triangle is equal to sum of two interior angles of a triangle.

So,

x + y = w

If x + y = w,

Then,

w > x

w > y

Draw a coordinate plane.
natulia [17]

The coordinate of points K, L and M is the location of the points on a coordinate plane

<h3>How to determine the missing coordinates?</h3>

The given parameters are:

K = (10, )

L = ( ,10)

M = (30, )

The question has missing parameters.

So, I will assume that the line is a perfectly horizontal line.

This means that the y-coordinates of points K, L and M are equal.

The y-coordinate of point L is 10.

So, we have:

K = (10, 10)

L = ( ,10)

M = (30, 10)

Assume that point L is halfway points K and M, then we have:

K = (10, 10)

L = (20, 10)

M = (30, 10)

See attachment for the diagram of the coordinate plane showing the line
