Hmm,
we see that the middle term is negative
that tells us that the factors must also be negative because if they were different signs then they would have to be 0,1, or -1,0 which wouldn't work because x doesn't factor out, well, if c=0, then it would get x=17 and 0 which doesn't work


well


what 2 numbers are 1 apart, and are negative and add to -17
-8 and -9
multily them
72

c=72
x^2-17x+72=0
if we factord
(x-8)(x-9)=0
theh zeroes are x=8 and 9

(9,-1); m=4/3 write an equation in point slope form for the line through the given point with the given slope
madreJ [45]
For this problem you are going to need to know the point-slope equation which is: 
y-y₁=m(x-x₁)

Now, m=slope and the x and y values are given to us already, so now we just plug our variables into the formula.

It should look like this: y+1= \frac{4}{3}(x-9)
Since all they are asking for is for you to put it into a formula this will be your answer.
