1 answer:
kirill [66]2 years ago
8 0

Answer:

Graph 1 ➡ y = 1/5 x + 3

Graph 2 ➡ y = 3x

Graph 3 ➡ y = -3x + 5

Graph 4 ➡ y = 1/3 x + 5

Step-by-step explanation:

Remember that slope is basically rise/run, where rise is up and down movement and run is left and right movement.

Also remember the formula for slope is y=mx+b, where m is slope and b is y-intercept. Additionally if y-intercept is 0 you don't write it.

Hope this helps :)

The circle passes through the point (−2, 3) with a center of (-4,6). What is its radius?
Ganezh [65]

Answer:

<u>radius = √13</u>

Step-by-step explanation:

Forming the equation :

<u>(x - h)² + (y - k)² = r²</u>

  • (x, y) = point on circle
  • (h, k) = center of circle
  • r = radius

Solving :

  • (-2 + 4)² + (3 - 6)² = r²
  • r² = 4 + 9
  • <u>radius = √13</u>

Convert the rectangular coordinates to polar coordinates with
NikAS [45]

Given:

Rectangular coordinate = (8, 6)

To convert:

Rectangular coordinate to polar coordinate with r > 0 and 0 ≤ θ < 2π.

Solution:

Let us find r:

r=\sqrt{x^{2}+y^{2}}

r=\sqrt{8^{2}+6^{2}}

r=\sqrt{100}

r = 10

Now, find θ:

$\tan \theta=\frac{y}{x}

$\tan \theta=\frac{6}{8}

Cancel the common factor 2.

$\tan \theta=\frac{3}{4}

$\theta=\tan^{-1} \left(\frac{3}{4}\right)

θ = 36.87°

The polar coordinates are (r, θ) = (10, 36.87°).
