Answer:
Step-by-step explanation:
Distance is calculated using this formula:
where (x₁, y₁) and (x₂, y₂) are the points. We are given (-3,8) and (-3,7). Therefore;
Substitute the values into the formula.
Solve inside the parentheses.
- -3 - - 3= -3+3= 0
- -7 - 8 = -15
Solve the exponents.
- 0²=0*0= 0
- -15²= -15*-15=225
A negative number for distance doesn't make sense, so the distance must be 15.
