d: 1
Looks good to me!! Yuh done good.
(x1,y1) = (-2,7)
m = -5
(x,y) = (a,2)
Forming the equation,
(y-y1) = m(x-x1)
y - 7 = -5[x - (-2)]
y - 7 = -5x - 10
y + 5x = -3
Putting the values of (x,y) we get,
2 + 5a = -3
5a = -5
a = -1
Answer:

Step-by-step explanation:
First, we change both denominators to the LCM (lowest common multiple) which is 8.

Since the denominators are the same, we can add the numerators.


or it can be written as

Yes all cubes are similar but their measurement is not similar
