Given two points: (x₁,y₁) and (x₂,y₂) the slope "m" will be:
m=(y₁-y₂) / (x₁-x₂) or m=(y₂-y₁) / (x₂-x₁)
In this case:
(4.5 , 13.5)
(-3.5 , -9)
m=(-9-13.5) / (-3.5-4.5)=-22.5 / -8=2.8125
Answer: the slope will be m=2.8125.
The Ratio Of Puppies To Kittens Is 12:36
Answer:
3
Step-by-step explanation:
f(x) = x^2 + 2x - 5
f(-4) = (-4)^2 + 2(-4) - 5
f(-4) = 16 - 8 - 5
f(-4) = 3
Answer:

Step-by-step explanation:
The y-intercept of a graph occurs when the function cross the y or vertical axis. This is also where x is equal to 0.
Therefore, we can substitute 0 in for x and solve for y.


Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve the exponent. Any number raised to the power of 0 is equal to 1.

Multiply.

The y-intercept is 2. So, when x=0, y=2.
Coordinate points are written as (x, y). The y-intercept is <u>(0,2).</u>
