Answer: 8 units
Step-by-step explanation:
To find the distance between 2 points, we want to use the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Since we are given the 2 points, all we have to do is plug them in.
[tex]d=\sqrt{(7-(-1))^2+(8-8)^2}[/tex] [parenthesis]
[tex]d=\sqrt{(8)^2+(0)^2}[/tex] [exponent]
[tex]d=\sqrt{64+0}[/tex] [add]
[tex]d=\sqrt{64}[/tex] [square root]
[tex]d=8[/tex]
Now, we know the distance is 8 units.
