The slope of a line is 1, and the y-intercept is -1. What is the equation of the line written in slope-intercept form?

1 answer:

3 0

The slope-intercept form is:
y = mx + b
where m = slope, and b = y-intercept.
You need a slope of 1, so m = 1.
You need a y-intercept of -1, so b = -1.
Replace m with 1 and b with -1 in the slope intercept form to get

y = 1x + (-1)

which simplifies to

y = x - 1

Answer:

<h3><u>Firs</u><u>t</u><u> </u><u>q</u><u>uestion</u></h3>

To find ? we use sine

sin ∅ = opposite / hypotenuse

From the question

The hypotenuse is 50

The opposite is 25

So we have

sin ? = 25 / 50

sin ? = 1/2

? = sin-¹ 1/2

<h3><u>Sec</u><u>ond</u><u> </u><u>q</u><u>uestion</u></h3>

To find ? we use tan

tan ∅ = opposite / adjacent

From the question

the opposite is 8

the adjacent is 33

So we have

tan ? = 8/33

? = tan-¹ 8/33

? = 13.62

<h3>? = 14° to the nearest degree</h3>

Hope this helps you

Kevin and Randy Muise have a jar containing 80 coins, all of which are either quarters or nickels. The total value of the coins

SCORPION-xisa [38]

Answer:

39 quarters and 41 nickels

Step-by-step explanation:

Let the number of quarters be x and nickels be y.

<u>Given:</u>

Quarter is 25 cents
Nickel is 5 cents
Number of coins is 80
Total amount is $11.80 = 1180 cents

<u>We have equations:</u>

x + y = 80
25x + 5y = 1180

<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>

25x + 5y - 5x - 5y = 1180 - 80*5
20x = 780
x = 780/20
x = 39

<u>Find the value of y:</u>

39 + y = 80
y = 80 - 39y = 41

<u>Verify:</u>

25*39 + 5*41 = 975 + 205 = 1180

The bisector of angle APQ passes through O and this is illustrated below.

<h3>How to illustrate the information?</h3>

From the information given, the center is O. and the circle passes through O and cuts at K.

In this case, it should be noted that the circles are equal according to the SAS test.

Here, AOB + APQ = 180° (Linear pair)

2AOB = 180

AOB = 90.

Therefore, the bisector of angle APQ passes through O.
