Dory and nemo go to taco bell for lunch. dory orders three soft tacos and three double deckers for $11.25. nemo pays $10.00 for four soft tacos and two double deckers. write a system of equations that represents the lunch orders for dory and nemo. use x to represent soft tacos and y to represent double deckers.

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
