Question

The axes range from negative 7 to 7 in one-unit increments. The line begins at point upper A in quadrant 2, crosses the y-axis, and ends at point upper B in quadrant 1.

To the nearest tenth of a unit, what is the distance between points A
𝐴
and B
𝐵
?

Answer 1

I don’t have the diagram, so I can’t read the coordinates of A and B. Could you either paste the picture or tell me the coordinates of A and B (count the grid squares)?

Once I have the coordinates (x1,y1) and (x2,y2) I’ll compute the distance using the distance formula:
distance = sqrt[(x2 − x1)^2 + (y2 − y1)^2]
and give the nearest tenth.
