Answer:
slope intercept form is : y = mx + b
where m is the slope and b is the y-intercept.
The slope, m = (y' - y)/(x' - x)
Is found using the two pints.
The apostrophe is used to denote the other point, different from point (x,y).
once you have the slope, m for the equation y = mx + b ; use one of the points as (x,y) to solve for b.
The answer is the 3rd question
2p/(4p²-1)÷<span>6p</span>³<span>/(6p+3)
=</span>2p/(4p²-1) × (6p+3)/6p³
2p/(2p+1)(2p-1) ×3(2p+1)/6p³
=1/[(2p-1)*p²]=1/(2p³-p²)
we need to get y alone so subtract 2x from both sides of the equation
2x+4y=12
-2x -2x
-----------------------
4y=-2x+12 now divide both sides by 4
y = -2x/4 +12/4
y = -1/2 x +3
