Find the slope between the two points: (3,-2) and (4,7)
cupoosta [38]
To find slope given two points, there is a formula you can use: (y2-y1)/(x2-x1). Y2 stands for the second y coordinate and y1 stands for the first y coordinate. The same logic applies to the x's. Let's assume that (3, -2) is x1, y1 and (4,7) is x2, y2. Let's plug them into the formula.

(7-(-2))/(4-3).
7-(-2)=9 for total y value.

4-3=1 for the x value.

Now we divide them.
9/1=9. 9=m. M is the variable commonly used for slope. Hope this helped!

I NEED HELP PLEASE, THANKS! :) Use the graph to determine the domain and range of the relation, and state whether the relation i
Mandarinka [93]

Answer:

Domain: All numbers greater than or equal to 0. By definition, the domain of a graph, is the possible x values.

Range: All real numbers. By definition, the range is all possible x values.

Not a function. A function has y value for every x value.

8 x 10^-3 is how many times as great as 4 x 10^-6
mamaluj [8]

For this case we can rewrite the expressions as:

3 * 10 ^ {- 3} = 0.003

That is, we run the decimal three times to the left.

4 * 10 ^ {- 6} = 0.000004

That is, we run the decimal six times to the left.

So:

0.003-0.000004 = 0.002996

So, we have that 3 * 10 ^ {- 3}is 0.002996 times bigger than 4 * 10 ^ {- 6}

Answer:

3 * 10 ^ {- 3}is 0.002996 times bigger than 4 * 10 ^ {- 6}
