To answer this question, you have to find the least common multiple of 5, 2, and 7.
1) Find the prime factorization of each of the numbers=5, 2, 7
2) Multiply the numbers: 5*2*7=70
3) Every 70 days he will do all three things on the same day
Answer:
y = 5x -7
Step-by-step explanation:
first find the slope using the formula y2-y1/x2-x1
-12 -3 -15
--------- = ---- = 5
-1 -2 -3
slope: 5
Now to find the intercept plug in the slope and the numbers into the equation then solve
y-y1=m(x-x1)
y - 3 = 5 (x -2)
y -3 = 5x -10
+3 +3
y = 5x -7
