1)FInd an equation of the line containting the given pair of points.
(8,0) and (0,5)
MY ANSWEAR: (5/8)X+5
2)Find an equation of the line having the given slope and containing the given point.
m=6 (8,1)
MY ANSWEAR: 6X47

1)
Firstly we need to find the slope of the line the two points are on by using the equation
m = (y2y1)/(x2x1)
m = (5  0)/(0  [8]) = 5/(0 + 8)
m = 5/8
Then use yy1=m(xx1) to find the equation of the line.
y  0 = (5/8)*(x  [8])
y = 5/8x + 5
So your answer is correct :)
2)
You can jump straight to the
yy1=m(xx1) equation.
y  1 = 6(x  8)
y  1 = 6x  48
y = 6x  48 + 1
y = 6x  47
So you got both parts correct :)
Well done!
