For class sandra has five cups of flour. she made 3 batches of cookies that each used 1.5 cups of flour. what is the amount of flour left after making the three batches of cookies, also write an expression.

Expression: 5 - 1.5b = flour left (b=batches)

0.5 cups of flour left

Im not certain on the expression but the answer is correct. Hope this helps!

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

answer: it is a.,b.,d.
