Answer:
y = 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 2) ← coordinates of intercepts
m = 
= 2
Note the line crosses the y- axis at (0, 2) ⇒ c = 2
y = 2x + 2 ← equation of line
They spent a total of $46.25
Here's how I got my answer:
Step 1: Add $18.00 and $16.40 together. Which is $34.50.
Step 2: Add $34.50 and $11.75, which will give you your answer, $46.25.
Answer:
3
Step-by-step explanation:
First, find the midline by averaging the highest value (2) and the lowest value (-4). In other words, do (2+-4)/2. You get the midline as -1. Now find the distance from the midline to the top. Distance from -1 to 2 is 3. Amplitude is therefore 3.
A^2 + b^2 = c^2
A*2 b*2
When you get the final answer of a and b after squaring you then add a and b and you get your answer C^2
