Well, FOIL it first:

First

Outside

Inside

Last

x*x=x^2

x* -4= -4x

x*3= 3x

3* -4= -12

Together, the simplified product is:

x^2 + -1x-12

So, the middle term is -1

Answer:

The middle term is - x

Step-by-step explanation:

Use Foil

F: x * x = x^2

O: -4 * x = - 4x

I: 3*x = 3x

L: 3 * - 4 = -12

F+O+I+L = x^2 - 4x + 3x - 12

F+O+I+L = x^2 - x - 12

What is the slope of the line through (-9, 6) and (-3, 9)? Choose 1 answer:

trasher [3.6K]

Given: Points (-9, 6) and (-3, 9)

Find: The slope of the line that goes through those two points

Solution: In order to find the slope of the line that goes through the points that were provided we have to use the slope formula. This formula subtracts the y-coordinates from each other and also the x-coordinates from each other to determine the rise/run which would give us the rate of change.
