Nana76 [90]

Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.

\frac{-1-7}{3-4}

Which reduces to 8/1=8.

The slope of your equation is 8.

Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.

Plug the slope in:

y=8x+b.

Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).

-1=8(3)+b

-1=24+b

Subtract 24 from both sides.

-25=b

Now plug this into the equation!

y=8x-25 is your final equation.

I hope this helps :)

Marty is explaining to Susan how to solve the following problem, -4 – (-5)
Alexxx [7]

Answer:

The correct answer is:

To subtract an integer, add its opposite; -4 + 5 = 1

Step-by-step explanation:

Marty is explaining to Susan how to solve the following problem, -4 – (-5)  

He told Susan that to subtract an integer, add its opposite.

We know that whenever we solve the two terms, first we multiply the signs.

It means that the negative sign outside the round bracket will be multiplied with the negative sign of -5

That is,

-4 - (-5)

By multiplying the signs we get the terms:

-4 + 5

=1

Thus the correct option is D....
