Answer:
y = -2x + 4
Step-by-step explanation:
First, find the slope by doing rise over run. I did this between the points (0, 4) and (2,0) This gives you -4/2 = -2.
Then, find the y-intercept, which is where the line goes through the y axis. This is at y = 4.
So, the equation is y = -2x + 4.

Answer:
Step-by-step explanation:
B is correct: We Divide it (the coefficient b) by 2 and square the result.
Answer:
(a-b+2)/3 = c
Step-by-step explanation:
a=b+3c−2
Add 2 to each side
a+2=b+3c−2+2
a+2 = b+3c
Subtract b from each side
a+2 -b =3c
Divide each side by 3
(a-b+2)/3 = 3c/3
(a-b+2)/3 = c
Answer: 210
Explanation: To find the least common multiple for the integers 30 and 35, we start by making a factor tree for each of our integers.
So 30 is 10 · 3 and 10 is 5 · 2.
35 is 7 · 5.
Notice that our 5's match up as factors of each of our integers.
When finding the least common multiple, we simply multiply all of our factors together but since the 5's match up,
we only multiply by a 5 once.
So our least common multiple or LCM is
5 · the 2 that doesn't match up · the 3 that
doesn't match up · the 7 that doesn't match up.
So we have 5 · 2 · 3 · 7 or 210.
