Find the distance between each pair of points
(-3,0) and (4,0)
I have no idea where to even start. Can someone help?

Can you picture the number line? (4,0) is 4 away from zero and (-3,0) is 3 away from zero so the answer is 7. Normally you would use the distance formula for the distance between two ordered pairs but both of these are on the x-axis, the number line.

d((-3,0) , (4,0))=
=sqrt( (-3-4)^2 +(0-0)^2 )
=sqrt ( 49)=7
you could have started by using the definition of the distance between two points.
It is in your textbook as well as in the notes you took when your teacher taught you

Distance formula
D = sqrt((x2 - x1)^2 + (y2 - y1)^2)
(-3,0) and (4,0)
D = sqrt((4 - (-3))^2 + (0 - 0)^2)
D = sqrt((4 + 3)^2)
D = sqrt(7^2)
D = 7

7. Distance means magnitude so you ignore the - on -3
so it becomes 3+4=7

remember this formula...the distance between 2 points is equal to the square root of (x2-x1) + (y2-y1)..your first point being (x1,y1) and your second point being (x2,y2) hope it helps. =D
