Answer:
ok sorry i could not put this into a formula im have to go but i will show you a really easy way.
Step-by-step explanation:
for number 1 i got (7,-1)
This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.
The correct way for doing number 1 is using the distance formula i believe but im running out of time
for the second one i got (3, -1/2)
we do this by using the midpoint formula.
The first picture is for number one and the second for number 2

Have you never added 2-digit numbers?
35 +27 = (30 +20) +(5 +7) = 50 +12 = 62
35/100 +27/100 = (35 +27)/100 = 62/100
0.35 +0.27 = 0.62
The basic idea, taught in 3rd grade, is to line up the decimal points of the numbers, add enough zeros on the right to make the numbers all have the same number of digits to the right of the decimal point, then add in the usual way. The sum has the decimal point aligned with the rest of the numbers.
