A conjecture and the flowchart proof used to prove the conjecture are shown.
pishuonlain [190]

Answer:

∠1 is supplementary to ∠3.

Step-by-step explanation:

Given information: ABCD is a parallelogram.

Prove: ∠1 is supplementary to ∠3.

Proof:

∠1 = ∠ADB

∠2 = ∠DBC

∠3 = exterior angle adjacent to angle D B C.

Statement                                         Reason

∠2 is supplementary to ∠3           Linear pairs

m∠2+m∠3=180°                             Definition of supplementary angles

m\angle 1=m\angle 2                            Alternative interior angles

m∠1+m∠3=180°                              Substitute property of equality

∠1 is supplementary to ∠3            Definition of supplementary angles

Hence proved.

Use the order pairs to find the linear equation in slope intercept form<br> (0,10) &amp; (3,2)
Virty [35]

y = \frac{-8}{3}x + 10 is the equation in slope intercept form

<em><u>Solution:</u></em>

Given points are (0, 10) and (3, 2)

We have to find the slope intercept form

Let us first find the slope of line

<em><u>The slope of line is given as:</u></em>

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

Here,

(x_1, y_1) = (0, 10)\\\\(x_2, y_2) =(3,2)

<em><u>Substituting the values we get,</u></em>

m = \frac{2-10}{3-0}\\\\m = \frac{-8}{3}

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Substitute m = \frac{-8}{3} and (x , y) = (0, 10) in eqn 1

10 = \frac{-8}{3} \times 0 + c\\\\c = 10

Substitute\ m = \frac{-8}{3}\ and\ c = 10\ in\ eqn\ 1

y= \frac{-8}{3}x + 10

Thus the equation of line in slope intercept form is found
