Hi there!
For a line to be PARALLEL, it must contain the same slope.
The given line has a slope of 4, so we can use the point-slope formula to solve:

y1 = y-coordinate of given point
x1 = x-coordinate of given point
m = slope
Plug in the values:

Simplify:

Answer:
Part A 73 Part B 113
Step-by-step explanation:
Fiona drives 3 1/2 hours on highway = 3.5 hours
average 60 miles per hour on highway.
Then 3.5 * 60 =210 miles
1 1/2 hours in the city = 1.5 hours
average 30 miles per hour in city
Then 1.5 *30 = 45 miles
So
Fiona drives 210 miles on highway and 45 miles in city.
Total of her trip to her grandmother's house equals:
210 + 45 = 255 miles
She drives 3.5 on highway and 1.5 in the city, then total driving should be:
3.5 + 1.5 = 5 hours
Average speed for the entire trip:
255 /5 = 51 miles
The pattern goes plus six, plus six, plus six. so the answer would be 19
4x+3=3(x+3)
4x+3=3x+9
4x-3x=9-3
x=6
So The Father is 24 and the Son is 6
