Question

Plot the points (-3, 4)(−3,4)(, minus, 3, comma, 4, )and (4, 4)(4,4)(, 4, comma, 4, )on the coordinate plane below. What is the distance between these two points

Answer 1

Remember, the plot of the point (a,b) in the coordinate plane correspond to the point with a value of a in the x axis and a value of b in the y-axis.

The distance between two points (a,b), (c,d) is:

`d=√((c-a)^2+(d-b)^2)`

Then, the distance between (-3,4) and (4,4) is

`d=√((4-(-3))^2+(4-4)^2)=√(7^2)=7`

The image below show the points in the coordinate plane.
