Find an equation for the line below.

Mathematics
1 answer:

Answer:

  y = -4/5x - 0.8

Step-by-step explanation:

A(-6, 4)

B(4, -4)

Find slope using the two points above:

m = (y₂ - y₁) / (x₂ - x₁)

   = (-4 - 4) / (4 - (-6))

   = -8 / 10

m = -4/5

Find y-intercept using m from above and anyone point, let's use (-6, 4):

y = mx + b

4 = -4/5(-6) + b

4 = 24/5 + b

b = -0.8

Use m and b from above to form equation of line:

y = mx + b

y = -4/5x - 0.8

Calcular x en: los datos q faltan
Taya2010 [7]
Answer:

x = 13

Step-by-step explanation:

No se exactamente como decir esto porque yo ayudo la majoria de los usuario en ingles pero hay que usar un método para describir a x

Un método que se llama Pythagorean theorem

Pythagorean theorem: a^2 + b^2 = c^2 donde a^2 = 5 b^2 = 12 y c^2 = x

Entonces…

5^2 + 12^2 = c^2

Nota: podemos ver que esto esta bien porque el sum de los dos lados suma el mas largo.

Ahora

25 + 144 = c^2

c^2 = 169

Pero eso no puede ser la respuesta porque no tiene sentido a que x sea un lado que mide 169 entonces tenemos que usar sqrt rt

sqrt rt de 169 = 13

x = 13

¡ HELP Plz !<br> Graph this line using the slope and y-intercept:<br> y=1/2x-1
Sladkaya [172]
-1 is your x intercept so the first point is going to be at (0,-1) and from there go up 1 and over to the right 2 and mark another point and so one
