Answer:

<em>m=1 y b=-2</em>

Step-by-step explanation:

<u>Ecuación de la recta</u>

La recta puede escribirse de varias formas. Una de ellas es la llamada punto-pendiente, donde construimos la ecuación conociendo estas dos variables.

La ecuación punto-pendiente se expresa de la siguiente forma:

y - yo = m( x - xo )

Donde m es la pendiente y (xo,yo) es el punto por donde la recta pasa.

Para calcular la pendiente usamos la fórmula siguiente:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Donde (x1,y1) y (x2,y2) son dos puntos de la recta.

Del gráfico extraemos los puntos (0,-2) y (4,2), entonces:

\displaystyle m=\frac{2+2}{4-0}=\frac{4}{4}=1

La pendiente m es igual a 1.

El parámetro b se conoce como la ordenada en el origen, y es el lugar donde la recta cruza el eje y.

Podemos ver claramente en el gráfico que eso ocurre cuando y=-2.

En resumen, m=1 y b=-2

u blow up 1/3.....1/3(12) = 12/3 = 4....so u blow up 4 out of 12...thats 4/12
ur friend blows up 5...he blows up 5 out of 12....thats 5/12

so 4/12 + 5/12 = 9/12....9/12 are blown up.....that leaves 3/12 or 1/4 left to blow up
