HI!!!

2. misty1212

from -5 to 4 is 9 units right from 2 to 9 is 7 units up by pythagoras your answer is $\sqrt{9^2+7^2}$

3. misty1212

if you are a slave to the formula you can use $d=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}$ you will get the same thing

so 81 +289=370 so the square root of 370?

5. misty1212

hmm no

6. misty1212

$$7^2=49$$

7. anonymous

ugh I hate calculators. ok so 81+49?

8. misty1212

yeah easier to do this one in your head yeah, $$\sqrt{130}$$

9. misty1212

or just go with C since it is C at least 87% of the time
