Since you only need two points to determine the slope, we use the first two, (0,15) and (2,9). The slope formula is (y2-y1)/(x2-x1), so (9-15)/(2-0)=(-6/2)=<em>-3</em>
Find two numbers with a sum of 20 and a difference of 14
Make two equations
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are
3 and 17
