Jon ran 21km (7+14 because robert ran 14 less so you add the 14 additional km to jon’s total)
First using the given two points we can find the slope (m) of the line

Thus the slope of given line is 1.
Using slope and a point (0,1) we can write the equation in point slope form as
y - 1= 1(x-0)
y - 1 = x
The above equation is the point-slope form of the equation.
<span>-10 < x - 9
</span><span>-10+9 < x - 9+9
-1<x, or
x> - 1</span>
You got this bro why do u need our help for
