Write the shortened form of each monomial.
a. 3 · b
b. n · m
c. 8 · s · t
d. 2 · q · r · s

Step-by-step explanation:

In algebraic expressions, we can omit the multiplication sign.

a. 3 · b = 3b

b. n · m = nm

c. 8 · s · t = 8st

d. 2 · q · r · s = 2qrs

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

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
