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.

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
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

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]

Answer:
a) ∠BAC = 30°b) ∠B = 120°c) ∠BAG = 150°Step-by-step explanation:
2x + 18 = 5x
18 = 5x - 2x
3x = 18
x = 6
a) find m∠BAC
substitute x=6 to ∠BAC
∠BAC = 2x + 18
= 2(6) + 18
= 30°
b) find m∠B
∠B = 180 - ∠A - ∠C
= 180 - 30 - 30
= 120°
c) find m∠BAG
∠BAG = 180 - ∠A
= 180 - 30
= 150°
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 :)
