which equation represents the line that passes through (5,8) and (9,2)

Answers

ASSUMING This is a straight line so we gotta the formula for a straight line which is y=mx+b, where m represents the slope and b represents the y intercept.

First, we know this line passes through (5,8) and (9,2) we can use these for finding the equations. When we know two points, we use this formula:

y-y=m(x-x)

The first y is 8 and the second one is 2
The first x is 5 and the second one is 9

Plug it in:

8-2=m(5-9)
6=m(-4)
6/-4=m <— simplify this
m= -3/2

*NOTE: another way to find m is by calculating it (y-y)/(x-x)

Now we know m, we have to find b.
All you gotta do is plug everything you know back into the equation y=mx+b

y=mx+b
y=-3/2x+b <— now plug in a point we know(x,y)

8=-3/2(5)+b
8=-15/2+b
8-(-15/2)=b
b=8+15/2
b=16/2+15/2
b=31/2 (now you can write be as a fraction or a decimal in your equation, depending on what your teacher told you to use)
*NOTE: it is best to use fractions instead of decimals as it is more accurate sometimes.

Now we know all the variables that need to be known, we just need to rewrite the formula of the equation so the teacher can see.

m=-3/2
b=31/2

We don’t need to plug in x or y since it could have different values (since a straight line has MANY co-ordinates)

SO OUR EQUATION IS=
y=(-3/2)x+31/2

An exterior angle of a triangle is 124°. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?

Answers

Answer:

62 degrees

Step-by-step explanation:

Let x be the measure of each non-adjacent interior angle.

By the remote interior angle theorem, the two angles mentioned add up to the exterior angle 124

x+x = 124

2x = 124

2x/2 = 124/2

x = 62  

So we have two interior angles of 62 degrees each. The third interior angle is 180-124 = 56 degrees. You can also find this by solving x+x+y = 180 for y Please brainliest

A game show contestant starts a game by answering three
questions incorrectly. Each incorrect answer costs the
contestant $900. What integer would represent the point total
for the contestant?
(Pls help)

Answers

Answer:

The negative integer would show for subtraction of money but when the person earns money the money will show in positive integer

The integer -3 will represent the total points for the contestant.

What are the different interpretation of negative numbers?A negative number is a number that is less than zero.Numbers that are to the left of zero on the number line.A number that is the opposite of a positive number. A negative number represents loss or absence of something.

According to the given question.

Let +1 point will be awarded to the contestant for giving the correct answer. And -1 point for giving the incorrect answer.

Number of questions for which the contestant given the answer

incorrectly = 3

Amount of money have to pay by contestant for each incorrect answer

= $900

Therefore, the amount have to pay the contestant for three incorrect questions = -3 × $900 = -$2700

Where,  a negative number shows the amount contestant has to pay or loss of the contestant.

Hence, the integer which represent the total point for the contestant is -3.

What is the slope and y-intercept of the equation 3x - y = 3?

Answers

Answer:

slope=3

y-intercept=-3

Step-by-step explanation:

put into slope intercept form to find your answer.

3x-y=3: move the variables to the right

-y=3-3x: change the signs

y=-3+3x: reorder terms

y=3x-3

Y = 3x - 3
subtract 3X from both sides
Divide both sides by -1
Dividing by -1 undoes The multiplication by -1 divide 3-3x by 1

Find the value of y when a = 7, b= 16 and c = -3 given that y = 5a + 8c - b

Answers

Answer:

-5

Step-by-step explanation:

Given expression:

          y = 5a + 8c - b

a  = 7,

b  = 16,

c  = -3

 Insert the given parameters and solve;

     y  = 5(7) + 8(-3) - 16

     y  = 35 - 24 - 16

     y  = 35 - 50

     y  = -5
