What is y use the picture down below. y=12x+3 y=12x−3 y=2x+3 y=2x−3

borishaifa [10]

Answer:

y = 2x - 3

Step-by-step explanation:

Slope-intercept form is y = mx + b

m = slope

b = y-intercept

If you look at the graph, the y-intercept is on (0, -3) which means the y-intercept is -3.

If you look at the slope, you can use the rise/run method. Let's use 2 as an example. We would turn it into a fraction, 2/1. You then want to use the rise/run method. Starting from the y-intercept, go up the amount of the first number, and then go right the amount of the second number. So we would go up 2 and 1 right.

So this is our answer, y = 2x - 3

Amrutha sold a watch for Rs1350 and suffered a loss of 10% then find a) loss b) CP

iVinArrow [24]

Answer:

HEY MATE HERE IS YOUR ANSWER

S. P. PF WATCH = 1350

LOSS % = 10%

C. P =

\frac{100}{100 - loss\%} \times s.p

100−loss%

100

×s.p

C.P= you should find it yourself for practice

Part 2

Gain percentage

\frac{gain \times 100}{c.p}

c.p

gain×100

= you should find it yourself for practice.

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..

Ksju [112]

Answer:

Slope = 27/11
AB = 29.15 u

Step-by-step explanation:

Given :-

Two points are given to us .
The points are A(7,15) and B(18,42)

To Find :-

The slope of the line .
The length of line AB .

We can find the slope of the line passing through the points $( x_1,y_1)$ and $( x_2,y_2)$ as ,

$\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}$

Plug in the respective values ,

$\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}$

Hence the slope of the line is 27/11 .

$\rule{200}2$

Finding the length of AB :-

We can find the distance between them by using the Distance Formula .

$\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }$

Hence the length of AB is 29.15 units .

jeka57 [31]

He can either measure the third side length, apply the Pythagorean theorem to find the height of the triangle, and then calculate the area, or he can find the measure of the included angle between the known side lengths and use trigonometry to express the height of the triangle and then determine the
