Y = -4x + 8

First you need to find the slope of the line.

The slope formula is m = y2-y1/x2-x1

If you plugged in the points it would be m = -4-4/3-1

so m = -8/2 = -4

so the slope is -4

now we need to write the equation of the line

for this u use point slope form

the formula for that is y-y2=m(x-x1)

so if you plug it in it would be:

y-(-4)=-4(x-3)

now you solve

y+4=-4x+12

y+4-4= -4x+12-4

y = -4x + 8

and now you have the slope of the line

I hope this helps! :)

Please help! posted picture of question

Rus_ich [418]

The given equation is in point-slope form.

The general form of an equation in point slope form is:

$y- y_{1}=m(x- x_{1})$

Here m is the slope and $x_{1}$ and $y_{1}$ are the coordinates of the point.

So in given equation the slope is 2/3, and the coordinates of point are (1,3)

Answer:

For part a you need to factor. X to the power of 2 is 2x. when you add it its turns into 2x+10x+16=0

2x+10x=12x

12x+16 will be your final answer

Find the radius of a circle if it’s circumference is numerically equal to its area

kotykmax [81]

Answer:

Step-by-step explanation:

hello :

if : r the radius ( r ≠0)

the circumference is : 2πr

the area is : πr²

so : πr² = 2πr

simplify by : r π you have : r=2
