Answer:
64cm^2
Step-by-step explanation:
3+1+4=8
8×8= 64cm^2
Answer:
-2
Step-by-step explanation:
The slope of a line when given two coordinates can be found using the formula
In this case, the first pair of coordinates are and and the second pair of coordinates are and .
Therefore:
= -2
= 7
= 3
= -3
Next, just plug these values into the slope formula from above.
The numerator is 10 (the two negative signs become a positive) and the denominator is -5.
can be simplified by dividing the numerator and denominator by -5 to give or simply -2.
Therefore, the slope of the line is -2.
