Answer:
23
Step-by-step explanation:
Let J represent Jiri's age. Then Pamela's age is 2J and the sum of their ages is ...
J + 2J = 69
3J = 69 . . . . .collect terms
J = 23 . . . . . . divide by 3
Jiri's age is 23.
Because all the coordinates of a line has the same slope. So, we can use any two of them to find the slope.
Try explaining how you worked the problem and how you did it
<span>A line thru (5,1) with slope of 3
y - 1 = 3(x - 5)
y = 3x - 15 + 1
y = 3x - 14
