Tome los datos de la figura y escriba los valores de my b

m=1 y b=-2

Step-by-step explanation:

Ecuación de la recta

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:

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

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

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

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
