Answer:
1.22222
Step-by-step explanation:
Use the equation y2-y1/x2-x1=m to find the slope.
Now, just insert your known values.
15-4/4--5=m
11/9=m
1.22222 is the slope.
Hope this helps!
First multiply, so 42 x 39, which equals 1,638, then estimate, round 42 to 40, and 39 to 40, and do 40 x 40 = 1,600 which is close to your answer, so good.
The sum of any integer and its opposite is equal to zero
