What is the value of p in the proportion below? 20/6 = p/12

O 2
O 10
O 40
O 72

p = 40

Step-by-step explanation:

20/6 = p/12

Reduce the fraction on the left side.

10/3 = p/12

Cross multiply.

3p = 10 * 12

Divide both sides by 3.

p  = 10 * 4

p = 40

step-by-step explanation:

compare

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
