What is the equation in point−slope form of the line passing through (−3, −4) and (0, 2)?

Mathematics

Answer:

y = 2x + 2

Step-by-step explanation:

To find the slope we do (Y1 - Y2)/(X1-X2) aka rise over run

So, m = (-4 - 2) / (-3 - 0)

m = 2

Now we have y = 2x +b

Notice one of our points is (0,2)

Since the x value of that point is 0, it is the y intercept.

In the slope intercept form b = y-intercept

Therefore b = 2

So, y = 2x + 2

Slope is found by dividing the change in ____ by the change in ____. x; y y; x
bekas [8.4K]

Answer:

Change in Y by the Change in X.

Step-by-step explanation:

Slope can be found by dividing the rise (change in y) by the run (change in x).

m =\frac{rise}{run} = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Given f(x)=3x+8 and g(x)=6x+6<br><br> then what is (f+g)(−1))<br><br> ?
tankabanditka [31]
(f+g)(-1)
=f(-1)+g(-1), so;
f(x)=3x+8
f(-1)=3(-1)+8
f(-1)=-3+8
f(-1)=5

g(x)=6x+6
g(-1)=6(-1)+6
g(-1)=-6+6
g(-1)=0
Finally:
f(-1)+g(-1)
=5+0
=5. As a result, (f+g)(-1) is 5. Hope it help!

Sally Jones pays $50.00 a month for group health insurance. There is a $300 deductible. Her medical bills for the last year were
neonofarm [45]

Given

Find out the  what was the insurance company's payment .  

To proof

As given

Sally Jones pays $50.00 a month for group health insurance

There is a $300 deductible

Her medical bills for the last year were $2,600.00

Linda's insurance company provided payment of 80% of the bills less the deductible.

Deductible

The  amount of money you will pay in an insurance claim before the insurance company starts paying you.

medical bill reducing the deductible = $2,600 -  $300

                                                             =  $2300

80 % is written in the decimal form

= \frac{80}{100}

= 0.8

than the equation becomes

Linda's insurance company provided payment  = 0.8× 2300

                                                                                = $1840

Therefore the the insurance company's payment be  $1840 .

Hence proved

The disctance between -8 and 5 on the number line can be found by which expression??
Ilia_Sergeevich [38]
It's A.  First of all, one of the only 2 things in math that will NEVER be negative is distances/lengths and times.  You have a distance here, so because one of your 2 numbers is negative, you have to take the absolute value of the difference.  -8-5 = -11, but the absolute value of that is 11.  Put the numbers on a number line and count the units between -8 and +5 and there are 11 units between those 2 numbers.
