Answer:
y= -3x+3
Step-by-step explanation:
First, write your current equation: y=-3x+b. Next, plug in the coordinate to your equation. It should look like this: 6= -3(-1)+b. Multiply -3 by -1 to get 3. This is what you should have: 6=3+b. Subtract 3 from both sides to get your y-intercept, 3. Go back to your original equation and plug in 3 to b. This is your final equation: y= -3x+3. So, the first answer is correct. Hope this helped!
The opposite of zero (0) is -0, which is always equal to zero~
Answer:
The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and
b (=y) for 5 weeks.
Step-by-step explanation:
Every week Jim runs 8 miles and bikes 12 miles.
Let the week be represented by w , running miles by r and biking miles by b
therefore
1w= 8r + 12 b
Multiplying both sides by 5
5(1w= 8r + 12 b)
5(1w) = 5(8r + 12 b )
5w= 40r + 60b
Jim runs 40 miles and bikes 60 miles in 5 weeks
The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and
b (=y) for 5 weeks.
The answer is written in the form (x, y) where x is written before y in the ordered pair. We treat running miles as x and biking miles as y.
