Answer:

2

Step-by-step explanation:

slope of line= \frac{y1 - y2}{x1 - x2}

slope of JK

=  \frac{3 - ( - 9)}{5 - ( - 1)}  \\  =  \frac{3 + 9}{5 + 1}  \\  =  \frac{12}{6}  \\  = 2

Answer:

Slope = 2

Step-by-step explanation:

Slope = \frac{rise}{run}

Slope = \frac{3+9}{5+1}

Slope = \frac{12}{6}

Slope = 2

How do you solve it?
MatroZZZ [7]

Answer:

<em>i: </em>x=-2, x=1

<em>ii: </em>x=-1/2

Step-by-step explanation:

Quadratic form:

You solve <em>i </em>by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.

(x+2)(x-1)=0

<em>"first"</em> would be x*x, which would equal x^{2}

<em>"outside"</em> would be x*-1, which would equal -1x, or -x

<em>"inside"</em> would be 2*x, which would equal 2x

<em>"last" </em>would be 2*-1, which would equal -2

Now you need to combine the terms so that they are one after the other

x^{2}-x +2x-2

Combine like terms, and you should get:

x^{2} +x-2

i Solution

<em>You need to get the variable by itself.</em>

<em>Subtract two from both sides</em>

x+2=0\\x=-2

<em>Add one to both sides.</em>

x-1=0\\x=1

ii Solution

<em>Add all the terms.</em>

x+2+x-1=0\\2x+1=0\\2x=-1\\x=-\frac{1}{2}

I would really appreciate the help! 15 points!

The slope would be 1/17 and then you would use that slope and plug it into the y=mx+b and solve for b

PLEASE HELP ASAP 30 PTS ):
ASHA 777 [7]

Answer:


Step-by-step explanation:

It's an exponential function but it is going in the negative direction. So now you know there has to be a negative in front of the function meaning it can only be c or d. Since we know its a exponential function. If we set x = 0, it will give us the y intercept. Which should be 1. However it is -2. Therefore it it multiplied by -2 meaning d is right answer
