Answer :
We would determine the distance from Robinswood to walmart by applying the formula for determining distance between two points which is expressed as
[tex]\begin{gathered} \text{Distance = }\sqrt[]{(x2-x1)^2+(y2-y1)^2} \\ \text{From the information given, } \\ x1\text{ = }3,\text{ y1 = - 5} \\ x2\text{ = }-\text{ 4, y2 = - 5} \\ \text{Distance = }\sqrt[]{(-4-3)^2+(-5--5)^2} \\ \text{Distance = }\sqrt[]{(-7)^2+(-5+5)^2} \\ \text{Distance = }\sqrt[]{49+0^2} \\ \text{Distance = 49 miles} \end{gathered}[/tex]
