molly is at the bank located at (-3,-4), she must drive to the grocery store next which is at (8,-4). Determine the distance she will have to drive? ​

Sagot :

Formula for distance:

[tex]d = \sqrt{ (x_{2} -x_{1)}) ^{2} + (y_{2} -y_{1)}) ^{2}[/tex]

Given:

x2 = 8

x1 = -3

y2 = -4

y1 = -4

Solution:

[tex]d = \sqrt{ (x_{2} -x_{1)}) ^{2} + (y_{2} -y_{1)}) ^{2}}\\d = \sqrt{(8-(-3)^{2} + (-4 - (-4)^{2}) } \\d = \sqrt{121+0} \\d = \sqrt{121}[/tex]

Answer:

11 units
