What is the equation of the line that passes through the point (−1,−3) and has a slope of 3?
Tanya [424]

Answer:

y= 3x

Step-by-step explanation:

The slope is just read. It is 3. It is the value of m in the general equation.

y = mx + b

y = 3x + b

To find b, use (-1,-3)

x = -1

y = -3                  Substitute into the general equation

-3 = 3(-1) + b       Simplify the right side

-3 = -3 + b          Subtract -3 from both sides

b = 0

Answer: y = 3x

Answer 5 plz!! Due tomorrow!
Roman55 [17]
Hey!

So, the denominator tells us how many pieces there are in the pizza. (4)

4 × 1 = 4 --- That's not enough for 11 people, if each person is supposed to get 1 slice.

4 × 2 = 8 --- Still Not Enough.

4 × 3 = 12 --- This is more than enough. 11 people can each have 1 slice.


So, your answer is: Cyrus should order 3 pizzas.
