Y2-Y1/X2-X1

3-0/2-0

3/2 which is the slope

Substitue in the slope intercept formula

So y=mx+b

Y=3/2x+b

Substitue the origin in the equation

0=3/2(0)+b

0=0+b

So B=0

Therefore g(x)=3/2x

solniwko [45]

<em>b</em><em> </em>for <em>books</em><em> </em>read. b=1x + 1. the amount of months he's been in the club goes for x and +1 because he already read a book before he joined. if you do easy math, he's been there for 8 months because he read 9 books. i probably got the equation backwards but this works both ways imo.

Melissa collected 14 bottles on Saturday and 9 bottles on sunday for recycling. on monday, she took all the bottles to the recyc
lina2011 [118]

Answer:

Option B is correct that is the amount she is getting per bottle is $0.15  

Step-by-step explanation:

We have been given the information that Melisande collected 14 bottles on Saturday and 9 bottles on Sunday

That means she has collected a total of 23 bottles

Let us assume that the amount she is paid for recycling is $b

Since she is left with $3.20 after the amount she gets for bottles we will get the equation below:

23b=3.20

Now, since she has to pay a one-time service fee equation will become

23b -0.25 =3.20

After simplification, we will  get

23b=3.20+0.25=3.45

b=3.45/23=.15

b=$0.15

Therefore, The amount she is getting per bottle is $0.15

HOPE THIS HELPS :)

Find the equation of the line that passes through (1,3) and is perpendicular to y = 1 − 2 x
egoroff_w [7]

Answer:

y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: y=mx+b where <em>m</em> is the slope and <em>b</em> is the y-intercept.

Perpendicular lines always have slopes that are negative reciprocals (ex. 1/2 and -2, 3/4 and -4/3)

<u>Determine the slope (</u><em><u>m</u></em><u>):</u>

y = 1 -2x

Rearrange into slope-intercept form:

y = -2x+1

Now, we can identify clearly that the slope is -2. Because perpendicular lines always have slopes that are negative reciprocals, a perpendicular line would have a slope of \displaystyle\frac{1}{2}. Plug this into y=mx+b:

y=\displaystyle\frac{1}{2} x+b

<u>Determine the y-intercept (</u><em><u>b</u></em><u>):</u>

y=\displaystyle\frac{1}{2} x+b

Plug in the given point (1,3) and solve for <em>b</em>:

3=\displaystyle\frac{1}{2} *1+b\\\\b=\displaystyle \frac{5}{2}

Therefore, the y-intercept is \displaystyle \frac{5}{2}. Plug this back into y=\displaystyle\frac{1}{2} x+b:

y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}

I hope this helps!
