Replace every x in k(x) with 9

2(9)^2-3(9)
18^2-27
324-27
297
K(9)=297

Help this is really hars

We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope

Turn both mixed fractions into improper fractions

2 3/5 = 13/5
1 4/7 = 11/7

now multiply the improper fractions

13/5 x 11/7

143/35 or 4 3/35
