(-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: 6X-47

Firstly we need to find the slope of the line the two points are on by using the equation

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

m = (5 - 0)/(0 - [-8]) = 5/(0 + 8)

m = 5/8

Then use y-y1=m(x-x1) 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

y-y1=m(x-x1) 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!
