Answer:
Step-by-step explanation:
There are multiple ways to solve this, but since two points are provided (8,7) and (7,p) and the slope is also given (m=4), we can use the formula for the slope.
Here,
Now we'll just solve for 'p'
Hence, the line passes through (8,7) and (7,3)

Domik weights 30 pounds more than his sister
Together they weigh 330 pounds
Let "x" represent the weight of Dominik's sister, then his weight can be expressed as "x+30"
And their total weight can be calculated as:
From this expression you can calculate the value of x:
x=150 pounds
x+30=150+30=180 pounds
Dominik weights 180pounds and his sister 150 pounds
