un automóvil se mueve inicialmente a una velocidad de 40km. sobre una hora y al cabo de un tiempo, alcanza la velocidad de 80km sobre hora. Determina la distancia que recorre si acelera a razón de 45 de 45 m sobre segundo

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
