In the input/output rule: y = 8x - 9 What would be the output of an input of 4? Write
only the number.

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

4400

step-by-step explanation:

how am i supposed to answer

step-by-step explanation:

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
