M= 5/7
explanation: Slope is equal to the change in
y
y
over the change in
x
x
, or rise over run.
m
=
change in y
change in x
m
=
change in y
change in x
The change in
x
x
is equal to the difference in x-coordinates (also called run), and the change in
y
y
is equal to the difference in y-coordinates (also called rise).

Answer:
The answer is the fourth option, 5.
87g divided by 10 = 8.7
8.7 times 7 = 60.9
60.9g of sugar is needed to make 7 cakes
Hope this helps! Feel free to thanks me, rate me 5/5 and make me brainliest!!!
The differences between he numbers are 19, so the answer is 58 + 19 = 71
