What is the slope form equation?

CaHeK987 [17]

Answer:

y= mx +c

Step-by-step explanation:

The point- slope form of an equation is

y= mx +c, where m is the gradient and c is the y-intercept.

You can find the value of m by using the gradient formula.

$gradient = \frac{y1 - y2}{x1 - x2}$

Then substitute the value of m found into the equation. Next substitute a pair of coordinates the line passes through to find the value of c. Substitute the value of c and you will obtain the point-slope form equation of the line.

<u>Here's an example.</u>

Point-slope form of an equation passing through (1, 2) and (5, 6).

① Finding gradient, m.

$m = \frac{6 - 2}{5 - 1} \\ m = \frac{4}{4} \\ m = 1$

② Substitute value of m into equation.

y= 1x +c

y= x +c

③ Substitute a pair of coordinates.

when x=1, y=2,

2= 1 +c

c= 2 -1

c= 1

Thus the equation of the line is y= x +1.

Someone please help!

lutik1710 [3]

Answer:

All are correct

Step-by-step explanation:

If Friend A gives 145 and Friend C gives 245 they already have a total of $390 out of the $700. So the missing amount is 310, half that for both friends and get 155, so the last 2 could both pay 155. No matter which way you put the number you will get the same answer. And as the communitive property states "The numbers on which we operate can be moved or swapped from their position without making any difference to the answer." and all of the answer choices apply to that statment.

2.46875 in fractionform

Kaylis [27]

2.46875 in a fraction form would look like this:

2.46875 =
= 2 46875/100000 =
= 2 9375/20000 =
= 2 1875/4000 =
= 2 375/800 =
= 2 75/160 =
= 2 15/32

I just kept simplifying it by dividing both numerator and denominator by 5 until I got its simplest form.

A race car is moving with a velocity of 144 kilometers/hour. The driver applies the brakes, and the car comes to a halt in 12.0

FinnZ [79.3K]

To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.

Bob won a $200,000 lottery. He invests part of the money in real estate with an annual return of 3% and the rest in a money mark

SVETLANKA909090 [29]

Answer:

Bob invested $50,000 in real state and $150,000 in a money market.

Step-by-step explanation:

Assuming that x is the investment in real state:

(200,000-x)*0.045 + x * 0.03 = 8,250

Apply distributive property:

(200,000*0,045) - 0.045x +0.03x = 8,250

9,000 - 0.045x +0.03x = 8,250

We must clear x:

- 0.045x +0.03x = 8,250 - 9,000

-0.015x = -750

x = -750/-0.015

x = 50,000

So, the invest in real state is $50,000.

$200,000 - $50,000 = $150,000 is the invest in a money market.
