Any ideas?

OpenStudy (anonymous):

i had b for number 1 and d for number 2

OpenStudy (anonymous):

but im not sure

OpenStudy (mathstudent55):

Do you know the distance formula? The distance, d, between points \((x_1, ~y_1) \) and \((x_2, ~y_2) \) is \(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)

OpenStudy (mathstudent55):

Your answer to the first question is correct.

OpenStudy (anonymous):

o ok thanks

OpenStudy (anonymous):

so i put the points where x,1 and x,2 go for the x axis and same for y?

OpenStudy (mathstudent55):

Can you label the quadrants in the following graph? |dw:1379941443663:dw|

OpenStudy (anonymous):

yeah lol i saw the mistake i made for the second one

OpenStudy (mathstudent55):

Yes, you substitute the values for x1, y1, x2, and y2 into the formula, the answer will be the distance.
