Answer:

I hope you will understand my explanation

Step-by-step explanation:

Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: 60° and 120° are supplementary angles.

Answer:

∠1 and ∠5

Step-by-step explanation:

Angles 2, 3 and 4 are taking up 180 degrees because it is 1/2 of a circle. That means angles 1 and 5 are also taking up 180 degrees because both the angles add up to a straight line

What is the equation for a line that passes through the points (5,-3) and (-10,15)?
4vir4ik [10]

Answer:

6x + 5y = 15\:or\:y = -1\frac{1}{5}x + 3

Step-by-step explanation:

First find the <em>rate of change</em> [<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{3 + 15}{-5 - 10} = -\frac{18}{15} = -1\frac{1}{5}

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:

15 = −1⅕[−10] + b

12

3 = b \\ \\ y = -1\frac{1}{5}x + 3

If you want it in <em>Standard Form</em>:

y = −1⅕x + 3

+1⅕x + 1⅕x

______________

1\frac{1}{5}x + y = 3[We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

5[1⅕x + y = 3]

6x + 5y = 15

_______________________________________________

−3 = −1⅕[5] + b

−6

3 = b \\ \\ y = -1⅕x + 3

y = −1⅕x + 3

+1⅕x + 1⅕x

______________

1⅕x + y = 3[We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

5[1⅕x + y = 3]

6x + 5y = 15

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

I am joyous to assist you anytime.
