What is the equation of a like that goes through the point 5,-2 and has a slope of. 6/5<br>

castortr0y [4]

Answer:

y= 6/5x -8

Step-by-step explanation:

The slope-intercept form (basically the form for the equation of a line)

y=mx+b

m is the slope

x is the value you want to plug in, or the x term in a point (x, y)

we know so far,

y=6/5x + b

so to find the missing value let's plug in the x & y value from (5, -2) and use the given slope

-2 = 6/5(5) + b

6 / 5 x 5/1 or 6/5 times 5 is 30/5 or 6

-2 = 6 + b

subtract 6 from each side to isolate the b value or y-intercept ( the point on the graph that is on the y-axis)

-8 = b

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.
