Use the slope intercept form; y=mx+b where m is the slope and b is the y-intercept
The answer is y = -2x + 10

Answer:
option 2
Step-by-step explanation:
Since the sign is greater than or equal to it will be pointing to the right since it includes -9 it will be a closed circle
Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old
