Question 3
Consider the parallelogram below with an area of 672 cm?
9x-12
16

Are of parallelogram = base * height

672 = b*h

or, (9x-12)* 16 =672

0r 9x-12 = 42

9x = 54

x=6

height =9x-12 = 54 -12 = 42

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
