Write an equation in point-slope form of the line that passes through the point (5,-12) and has a slope of m= -2/5

Answers

Answer:

I hope that it will be help full for u

Step-by-step explanation:

As we know point slope form ,

(Y- Y1) = m (X- X1)

As given data ,

m = -2/5

(X1,Y1) =  (5, -12)

X1= 5 , Y1=  -12

putt in the above equation these values, we get

Y-(-12) = (-2/5) ( X-5)

Y+12=(-2/5)X+2

Y= (-2/5)X -10  Ans   ,ITs also an answer but if you want to simplify more ,

taking LCM we get

Y  = ((-2)X-50)/5

What is the y-intercept when a line has a slope of 3 and passes through
the point (2, 7)?

Answers

Answer:

The y-intercept is (0,1)

Step-by-step explanation:

So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).

Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.

y-7=3(0-2)

y-7=3(-2)

y-7= -6.

-6+7= 1, so y=1

The ordered pair is then (0,1). Hope this was useful :)

Answers

Answer:

c = 3[tex]\sqrt{6}[/tex]

Step-by-step explanation:

triangle is right isosceles so both sides equal 3[tex]\sqrt{3}[/tex]

can use pythagorean theorem which is square each leg and set it equal to the hypotenuse (side 'c') squared

(3[tex]\sqrt{3}[/tex])^2 +  (3[tex]\sqrt{3}[/tex])^2 = c^2

(9x3) + (9x3) = c^2

27 + 27 = c^2

54 = c^2

c = [tex]\sqrt{54}[/tex]

simplify  [tex]\sqrt{54}[/tex] to equal = [tex]\sqrt{9}[/tex] x [tex]\sqrt{6}[/tex] which simplies to 3[tex]\sqrt{6}[/tex]

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                               Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
