Plz help 13 points!!!
love history [14]
Hello!

So, you have to plot the points on the graph. 

Your point is (4, -3/4)   so, plot the 4 on the x-axis, and the -3/4 on the y-axis. 
Go to the right on the x-axis 4 units to get to  (4, 0)  and from there go <em>down</em> (becuase it is a negative (-3/4))  3/4 of a unit.


I have attached an image of what it looks like below.

I hope this helps :))

Answer:

Step-by-step explanation:

x^2 - 9x - 70

we need to find two numbers whose sum is -9 and product id -17

The numbers are -14 and 5

By splitting the middle term,

x^2 - 14x + 5x - 70

= x ( x - 14 ) + 5 ( x - 14 )

( x + 5 ) ( x - 14 )

Hope this helps
