Answer:

3x - 9

Step-by-step explanation:

in expressions, we don't get the value of the unknown so, we just workout  by putting the like terms together.

(4x + 2x - 3x) - 9 = 3x -9.

find the equation of a straight line joining the points (6,9) and (4,7). Please help im bad at mathematic :( and please do a cal
quester [9]

Answer:

y = x+3

Step-by-step explanation:

First step is to find the slope

m = ( y2-y1)/(x2-x1)

   = ( 7-9)/(4 - 6)

   = -2 / -2

  = 1

The we can put is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 1x+b

Putting in one of the points

9 = 1*6+b

Subtracting 6

9-6 = b

3=b

y = 1x+3

y = x+3
