What is slope-intercept form? Why do we write equations using this form?

Mathematics

Brums [2.3K]3 years ago

Slope intercept form is y=mx+b
m=slope
b=y-intercept

the slope is the rate of change of the graph, basically rise/run (change in y divided by change in x)

the y intercept is where the graph intercepts the y axis





we usually use this form because we can find the slope and find where it hits the y axis.
there are other forms that may be helpful later on, but this one is usually the easiest form to find from a graph

Brrunno [24]

The Ratio would be 43:100.

Lets simplify the problem,

Expected increase of nurses = 711900

Expected increase of physicians = 168300

Ratio = Expected increase of nurses / Expected increase of physicians

Ratio = 711900 / 168300

= 43/100

Ratio = 43:100

Need Help With Math. One Question
alina1380 [7]

Answer: 2 < x < 16

The triangle inequality theorem says that if we have a triangle with sides a,b,c then

b-a < c < b+a

with b being longer than 'a'

In this case, a = 7 and b = 9 and c = x

so we have

b-a < c < b+a

9-7 < c < 9+7 .... replace a with 7, replace b with 9

2 < c < 16

2 < x < 16 .... replace c with x

So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.

Use the equation below to answer the question.
Ratling [72]

Answer:

The equivalent equation is correctly matched with a key feature of the graph is

y = 3(x + 2) highlights that the x-intercept is at -2.

Step-by-step explanation:

Given:

y=3x+6

Solution:

The Given Equation is in Slope - Point Form i.e

y=mx+c

Where,

m=slope\\\\c=y-intercept

On Comparing the given equation with above we get

slope=m=3\\\\y-intercept =6

Now we Know that

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

There are two intercepts:

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.

For x-intercept

Put y = 0 in

y=3(x+2)

0=3x+6\\\\3x=-6\\\\\therefore x=\dfrac{-6}{3}=-2

∴ x-intercept of

y=3x+6

x-intercept = -2

The equivalent equation is correctly matched with a key feature of the graph is

y = 3(x + 2) highlights that the x-intercept is at -2.

A $17,000 T-bill is purchased at a 2.75% discount rate for 20 weeks.
SVEN [57.7K]
The effective rate of interest to the nearest hundredth of a percent is 2.75%

Given:
T-bill value $17,000
purchased at a discount rate of 2.75%
term of 20 weeks.

An effective rate of interest is also referred as the DISCOUNT RATE, market interest rate, the internal rate of return, the annual percentage rate, and yield to maturity. 

Since the discount rate is given, it is also the effective rate of interest.
