First you need to find the slope of the line using the given coordinates of the two points.
The slope of the line = (1-4)/(4-3) = -3
Then you choose one pair of the coordinates given, either (3,4) or (4,1) , up to you, to find the equation of the line.
If you choose (3,4)
Then
(y-4)/(x-3) = -3
(y-4) = -3x+9
y = -3x+13
If you choose (4,1),
Then
(y-1)/(x-4) = -3
y-1 = -3x+12
y = -3x+13
So, F(x)=-3x+13
I’m pretty sure this is correct.
3.15. Just find the unit rate which is 1.5 and multiply that by 3
The first step to finding the equation of a line when 2 points are known....
the first step would be to use the slope formula to find the slope of the line
